Hello Community,

Doing a fresh post as I didn't realize the previous post was repost from r/chrome_extensions and I don't want to delete it as it has one upvote other than mine but if the moderators mention that it has to be removed I will.

The original post is below with a few edits.

I had an issue that I would run into when trying to find multiple words on a webpage and found a few addons/extension that do the job but wanted to build something more to my liking. Spent sometime with Claude code and wala let me present to HueMark – Multi-word highlighter it supports up to 6 terms for now and 13 languages available on Chrome/Edge/Firefox.

https://addons.mozilla.org/en-US/firefox/addon/huemark-multi-word-highlighter/

https://microsoftedge.microsoft.com/addons/detail/kgfekpgoffpafdpopoeelmcnjdpgiakc

Pros:

·        The shortcuts work out of the box for Firefox

·        The PDF highlighter works out of the box on Chrome/Edge not Firefox

Cons:

·        The shortcuts don’t work out of the box for Chrome/Edge (Edit: the shortcuts are working out of the box now)

o   Please add them

edge://extensions/shortcuts

chrome://extensions/shortcuts

o   use the following if not already overlapping with any other shortcuts or whatever is comfortable for you

§  alt+shift+right arrow to open/minimize extension

§  alt+shift+up/down arrow in minimized mode to jump between matches

§  alt+shift+left in minimized mode to cycle between terms

·        For pdfs on Firefox click on “open pdf” which opens the pdf viewer and then use ‘open’ in pdf viewer and browse to the pdf to use HueMark.

Did I mention it works on PDF’s? (Not in a convenient way on Firefox Edit: apparently, it is working conveniently now)

I know it may not matter much but I have added a colorblind feature as well. I have a friend (drifted apart now), sometimes I would help him with his coding problems when I would sit on his machine, his IDE used to feel like a mess to me, color wise, I never realized it until he asked to borrow my “Blue” pen drive which was in fact purple and that’s when I realized he was colorblind. So, kind of added that for him even though he may never have much use for this 😊

The entire project is open sourced on Github under the MIT license

 Looking for feedback and suggestions. Thank you!

Edit: Thanks for that one up vote on the previous repost!!!

Hi everyone!

I recently published my first Firefox extension, Savlix, and I'd love to get some feedback from the community.

I built it because I wanted a better way to save useful text from websites — especially AI prompts, code snippets, research notes, and information I might need again later.

Savlix lets you:

- Save selected text and automatically preserve its source URL.

- Organize snippets with categories, tags, colors, and notes.

- Search your collection instantly.

- Use a customizable sidebar with Page-Shifting Mode, which moves the webpage aside instead of covering its content.

- Choose between five themes and nine interface languages.

- Keep your snippets locally in Firefox's extension storage.

- Export and import your collection as JSON.

It also includes pinned snippets, duplicate detection, configurable sidebar positioning, and backup reminders.

It's free, requires no account, and is available on Firefox Add-ons:

https://addons.mozilla.org/en-US/firefox/addon/savlix/

This is my first public release (v1.0.0), so I'd especially appreciate feedback on usability, bugs, and features you'd like to see improved.

Thanks for checking it out!

The addon is found here: https://addons.mozilla.org/en-GB/firefox/addon/reddit-mass-comment-editor/

This addon allows you to:

• Perform mass search and replace / randomize operations on your comments/posts
• View, edit, randomize individual comments/posts
• Load comments/posts after a specific comment/post (via ID), allows you to operate on specific batches of comments/posts instead of trying to process all at once
  
• Filter down comments/posts to a specific subreddit
• Filter comments/posts by date range
• Create comments/posts backups (JSON format)
• Convert Reddit search pages with search results into .json files
• Load .json comment files into the addon for processing
• View a console log of all of its actions
• View reposts of mass edit/randomise operations - succeeded/failed/skipped items, as well as copy item IDs from each of these categories. Reports are saved locally, and can be renamed or deleted.

What was updated:

• Added post support. Now you have 3 modes - loading comments only, posts only, or posts + any of your comments in those posts. First two modes are fast, since they load posts/comments in batches of 100, while the last mode is slow - it requires an API call for each post to find user's comments in said post.
• Added a button to view the corresponding comment/post on Reddit (basically just opens the permalink in a new tab)
• Added an ability to display all loaded items. This can also be used for searching - since all text is visible, just search using Firefox's own Ctrl+F search.
• Added an ability to load posts/comments via IDs loaded from a CSV file. This allows you to use files Reddit's profile data export files to access all your comments or posts, starting right from the account creation, instead of being limited by 1800 latest ones like usual.
• added more labels for comments/posts, indicated deleted items along with the removal reason if available, and showing if the post is an uneditable link/media post
• added reports of mass edit/randomise operations. Saved locally, can be renamed / deleted.

Comment randomisation example:

Before:

A test comment #1, written purely for randomisation purposes to see how the word replacement works. Generally, the most commonly repeating words that define a sentence structure are kept as is, along with the punctuation, while everything else would be replaced.

After:

A food problem #4, receive reload for accreditation attitude to let how the puts enforcement bunch. Therefore, the most normally filtering scale that suffer a equality passenger are pull as is, below with the consultants, while technology over would be equipped.

Hi everyone, I made a Firefox extension called Tabernacle to help me group and organise my tabs. I’ve been using it for a while and decided to release it in case anyone else finds it useful.

It adds a sidebar where you can put tabs into folders and subfolders, nest related tabs under each other, and drag things around to organise them.

A few things it can do:

• Open a folder to see just its tabs, so you can focus on one thing at a time.
• Search tab titles, URLs and folder names, including inside collapsed folders.
• Use Firefox containers, with the option to set a default container for each folder.
• Pin tabs and folders so they stay accessible wherever you are.
• Find recently viewed tabs and folders, and reopen closed tabs.
• Follow your Firefox theme or use a monochrome appearance.

You can see screenshots and find the download on my website. The source code is on GitHub too.

It needs Firefox 142 or newer. If you give it a go, I’d be interested to hear how you get on, especially if anything feels awkward or doesn’t work as expected.

Edit:
Regarding containers, if a folder is set to use a specific container, new tabs created there will open in that container. It just sets the default for new tabs meaning tabs in different containers can be dragged into any folder and their container won't change.

Host Imagus Bridge (HIB) 2.1.5 – a companion for Imagus Reborn that fixes previews on hosts Imagus can't resolve (Firefox)

If you use Imagus Reborn, you've probably hit links where the preview just spins forever: product pages with several images, intermediate image-host pages, redirects, embedded video players. HIB is a small Firefox add-on that works alongside Imagus Reborn to resolve those. It's Imagus-first: if Imagus already shows a preview with your own Sieves, HIB stays out of the way. It only steps in when Imagus actually fails on a supported site.

What it does

• Built-in image gallery: resolved images open in a viewer with previous/next buttons, an image counter, and Esc or a close button. The size is configurable (automatic, 960x540 up to 4K, or custom).
• Fallback after a failed preview: when Imagus shows the gray spinner and gives up, HIB opens its own gallery and dismisses the stuck spinner.
• Supported so far: DLsite product galleries, Sukebei external image links, Sankaku fallback, AnimeID and NHPlayer videos (with subtitle handoff), and the OUO, TurboImageHost, imagehost.website, OrangePix/imgpv and XXPICS image hosts.
• You choose which sites it runs on from the toolbar popup. It collects no data.

Screenshots

1. With the optional custom Imagus Reborn Sieve (HIB_v2_DLsite_Gallery), the gallery opens in the normal Imagus popup and the arrow keys go through the images. https://raw.githubusercontent.com/molitar/host-imagus-bridge/main/screenshots/1-imagus-sieve-gallery.png

2. Without that Sieve, HIB falls back to its own built-in gallery, shown here with previous/next buttons and the image counter. https://raw.githubusercontent.com/molitar/host-imagus-bridge/main/screenshots/2-hib-native-gallery.png

3. The toolbar popup, where you pick a preset gallery size or custom dimensions. https://raw.githubusercontent.com/molitar/host-imagus-bridge/main/screenshots/3-gallery-size-options.png

Install

• Mozilla add-ons (signed): https://addons.mozilla.org/en-US/firefox/addon/host-imagus-bridge/
• GitHub (source, releases, the optional Sieves): https://github.com/molitar/host-imagus-bridge

Requires Imagus Reborn. Support depends on each website and can break when a site changes, so bug reports and site requests are welcome as GitHub issues or here in the comments.

Ever lost a long comment because you accidentally closed a tab? 😅

I built a Firefox extension called Unsent Text Guard to help prevent that from happening.

I'd be really happy if you gave it a try! It's my own little project, and I'd love to hear your feedback and suggestions to make it better. 🙏

🔗 https://addons.mozilla.org/en-US/firefox/addon/unsent-text-guard/

Thanks for supporting an independent developer! ❤️

I made a Firefox extension that gives SoundCloud a true black theme with any accent color you want

https://addons.mozilla.org/firefox/addon/tintcloud/

If you are using Firefox browser, then try this AddOn: https://addons.mozilla.org/en-US/firefox/addon/batch-downloader-for-instagram/ and don't forget to donate and support the developer ...

next features will be coming like selecting & downloading multiple posts,

I built a Firefox extension called Highlight Notes because I kept losing useful information while reading articles, researching topics and going through long Gmail and ChatGPT conversations.

Bookmarks helped me find the page again, but not the exact paragraph or sentence I wanted to remember.

I wanted something simple that would let me highlight text, attach my own notes and find everything later without needing an account or subscription.

So I built Highlight Notes.

https://addons.mozilla.org/en-US/firefox/addon/highlight-notes-free/

What it does:

• Highlight text in different colours and attach notes.
• Works on websites, Gmail, Reddit and ChatGPT conversations.
• Automatically restores highlights when you revisit a page.
• Search your saved highlights and notes in one library.
• Export annotated pages as PDFs, including long pages and conversations.
• Keep everything stored locally in Firefox without creating an account.

Why I built it

Many highlighting tools work well on ordinary articles but struggle with interactive websites like Gmail and ChatGPT. I wanted something that worked across both.

I also didn’t want basic highlighting and note-taking to require an account or ongoing subscription.

The Firefox extension is free for unlimited local highlights and notes, with three PDF exports included.

There is optional cloud sync for people who use multiple browsers, but it isn’t required for local use.

A few limitations

• Cloud sync is optional and requires Pro.
• Some websites with complex or frequently changing layouts may not restore highlights perfectly.
• The free version includes three PDF exports.

I’m the developer, and this is an independent side project built in my own time.

I’d appreciate feedback from Firefox users, particularly anyone who regularly highlights research articles, Gmail threads or ChatGPT conversations.

Firefox's built-in sidebar chatbot doesn't include Grok, and you can't customize it. It also forgets your conversation, so every time you open it you start afresh. SideGrok is my fix for that. It keeps your conversation in the sidebar so you can pick up where you left off. It also has a handy shortcut that toggles the drawer.

I'd love feedback or feature ideas.

I am the developer behind ScamsShield, a project by AWARAN. I spent nine months building it and would like feedback from Firefox users on one specific part: whether the result explains what to verify next after a suspicious message or link.

The Firefox listing is https://addons.mozilla.org/en-US/firefox/addon/scamsshield/

The product website is https://scams-shield.com

For example, an unexpected delivery payment request should leave you with a useful next step, such as checking the delivery through the carrier you already know. A label saying suspicious is only part of the answer.

Some features require payment. Before installing, please read the current permissions and privacy policy on the listing. It requests access to browser tabs and data on websites, so I would also appreciate specific feedback on whether the purpose of that access is explained clearly.

An assessment can be wrong and is not a guarantee that a message or website is safe. If you try an example, use an invented message and leave out private information.

I am sharing my own product. I am especially interested in what feels unclear, what you would want to verify yourself, and whether the explanation actually helps.

Thanks in advance.

Update, 10 October: I have finished this round of website work and am focusing on the desktop extension. For Firefox, please use the Mozilla listing already linked above. It is a separate package, so please judge the version on that listing rather than assume it matches the Chrome release.

The current extension overview is https://scams-shield.com/extension. I would especially value feedback on whether the website warning gives a reason you can understand, and whether the permissions explanation makes it clear why access to websites is needed. Please do not visit a real scam site just to test it. A warning or a clear result is not a guarantee.

Hi! I'm a platform engineer and I just published my first Firefox add-on. I built it because I kept reading CI and Kubernetes logs in the browser and comparing a passing and a failing run by eye.

What it does:

- Opens any raw log (GitHub Actions "View raw logs", Jenkins console, a .log or .gz file) as a fast, searchable viewer: levels in colour, stack traces kept with their error, 150k+ lines

- Compare two logs with "Ignore timestamps, IDs and durations", so only the lines that really changed are left

- Filter structured logs by fields: level=error service=payments duration>500

- Groups the same error across pods, bookmarks with notes → a Markdown report for a ticket

- Flags leaked tokens and passwords in logs and masks them before you share

- Dark mode for any site (Ctrl+Shift+. in Firefox) and JSON / JWT / Base64 / cron tools

Free and open source, no account, no analytics, nothing leaves your browser. Every release is tested in real Firefox in CI before it goes out.

Add-on: https://addons.mozilla.org/firefox/addon/logbeam/

Code: https://github.com/andronaft/Logbeam

It's a new add-on, so feedback is very welcome. What's missing for the logs you read?

Hello everyone!

About a year and a half ago I shared Focus Flow Monitor here, a small Firefox addon I built to track where my time online was going and to block the sites that kept pulling me away. A lot has changed since then, mostly because of the feedback I got from people here and in the reviews, and today it reaches version 1.0. 🎉 For anyone who has not seen it: it tracks the time you spend on websites, shows you where it went, and lets you block or limit the distracting ones. Everything stays in your browser. No account, no analytics, nothing is sent anywhere. ✨ What's new since that first post

• 🍅 Tomato Clock: a Pomodoro timer in the popup, with optional notifications. It can block your distracting categories while a work session is running.
• 🎯 Focus profiles: allow only the websites and categories you need for a particular activity.
• 🏁 Goals: daily or weekly targets or budgets for productive time, a category, or a single website.
• 📈 Insights: a focus score, and a weekly summary that compares this week with the last one.
• 🚦 Smarter rules: scheduled blocking, exceptions inside a broader block, and daily, weekly or monthly time limits.
• 🌟 Redesigned popup: today's summary, hourly activity, the timer, and quick actions for the site you are on.
• 🗂️ More control over your data: backup and restore, exclude websites from tracking, and delete history for a website or a date range.

🔒 Still privacy-first Your data is stored locally in Firefox and never leaves it. The code is open source under MPL 2.0, so you can check that for yourself.

I build this in my spare time, so every bit of feedback helps. If something is broken, confusing, or missing, tell me here or open an issue on GitHub. And if the addon is making a positive impact on your online habits, a rating or review on the addon page would mean a lot. Thank you to everyone who tried it, reported bugs, and suggested features along the way. Enjoy the update!

Hey everyone,

A while back I shared Reframe & Sift for YouTube, a small extension for taking back some control over YouTube's layout. Since then YouTube rolled out a change to the video metadata that a lot of people (me included) find harder to read.

Before:

Channel Name
218M views • 9 months ago

Now:

Channel Name ▷218M 9mo ago

Everything got squeezed onto one line, "views" is gone, the date is abbreviated to "9mo ago", and there's a little play icon jammed in front of the number. It's denser, sure, but I kept misreading the view count as something else entirely.

So I added an option that puts the old format back:

• "views" is restored after the number
• the leading ▷ icon is removed
• the channel name goes back on its own line
• the • separator returns between views and date
• abbreviated dates get expanded again ("9mo ago" → "9 months ago")
• it also applies to the end screen (the suggested videos at the end of a video)

It rebuilds the text from YouTube's own accessibility labels rather than guessing, so the numbers and dates are the real ones. Works on the homepage, subscriptions, and the watch page.

The rest of the extension is unchanged — quick recap:

• Customize grid columns / thumbnail size on the homepage & subscriptions
• Hide videos and live streams below a view-count threshold (fully adjustable)
• Hide homepage sections (Shorts, mixes, recommended) and filter by keyword
• Hide live chat while watching streams
• Collapse the header / resize the video in theater mode
• Custom colors for the header, sidebar and filter bar

Grid customization and the view-count filter are free forever. The rest, including this new one, is a 7-day trial and then a small one-time unlock.

It's an unofficial third-party tool, not affiliated with YouTube or Google. YouTube UI changes break things from time to time — this one is a good example — and I patch them as they show up.

Feedback very welcome, especially if you find a spot where the old format doesn't come back properly.

I build Konode, a browser sync extension with no Konode account and no Konode server. It syncs your bookmarks, open tabs, history and extension list to storage you already own (Google Drive, a GitHub repo, or any WebDAV server), with optional end-to-end encryption. It runs on Firefox and on Chromium browsers like Helium, Brave and Chrome.

1.4.0 is live on both Firefox Add-ons and the Chrome Web Store.

Now in 8 languages

Italian, Russian and Traditional Chinese are new, next to English, Hungarian, German, Spanish and Simplified Chinese. Traditional Chinese is its own translation with the words used in Taiwan, not Simplified Chinese converted character by character, and a native speaker reviewed it. Konode follows your browser's language, so there is nothing to set.

Japanese and Estonian are in progress. If you want your language in it, it is edited in the browser, no coding and no GitHub account needed: https://hosted.weblate.org/projects/konode/

Fixes worth knowing about

• Deleting a folder now removes it on your other devices too, instead of leaving it behind empty. And on Firefox, a deleted folder no longer comes straight back.
• Firefox no longer re-adds the same history from your other devices on every sync.
• Restoring bookmarks from your browser's own backup is no longer undone by the next sync, and a Konode restore point puts bookmarks back where they were instead of at the end.
• On Norton Neo, a New Tab bookmark no longer multiplies into thousands of copies.
• The setup screen no longer breaks when your browser auto-translates the page.
• Cancelling Google Drive sign-in no longer signs you out of Drive.
• Settings → Activity keeps up while it is open, and the device list shows when each device really synced last.

New storage option: a Nutstore (坚果云) card, for anyone in mainland China, where Google Drive can't be reached.

Hi everyone. I’m looking for someone who could help port Ears Audio Toolkit from Chromium to Firefox.

The main reason I’m still using Chrome is this extension. I’d really like to move to Firefox, but without Ears Audio Toolkit it’s basically the one thing keeping me on Chromium.

I’m looking for a true 1:1 port, not a simplified version — ideally with all existing features working exactly as they do in the Chromium version, including the same audio processing and functionality.

I’d also like to have a Java version/port of the same functionality because I want to integrate it into one of my own projects.

I’m asking for both because I tried looking into it myself, but I’m not experienced enough with this kind of thing. From what I understand, the audio pipeline / sound transmission logic is different, and I don’t really know enough about browser audio APIs and Java audio processing to reproduce it correctly.

If someone is interested in doing this, it would be great if the Firefox port and Java implementation could be published on GitHub so they can be maintained and improved by the community.

Thanks!

One thing that has always irritated me about Firefox was that it didn't have a global media controls panel like Chrome. There were some extensions that tried adding these controls, but they didn't have all the same features as Chrome's.

So, I made my own (nearly) 1-to-1 copy of Chrome's media controls for Firefox with some extra features like media pinning, volume control, and viewing YouTube chapters. You can check out the extension and source code here:
