Hey! This is my first time using a browser other than Chrome, and I'm currently learning web development. Do you have any tips or recommendations for getting the most out of this browser?

My first impressions are really positive! I'm loving the vertical tabs, tab groups, and all the customization options. I also really appreciate that it's open source and more privacy-focused than Chrome. The developer tools are great too, and I actually like that there's no AI integration.

Overall, it feels really solid so far, and I'm excited to explore it more!

I just wanted some MP3s... This is for Windows 11 btw.

It also happens for Tumblr and Discord, too, not just this website.

There's nothing dangerous about this site, I've been using it for 5 years with no issue. Same with the others but longer. WTF am I supposed to do now???

I've developed this new add-ons to customize Firefox and I would love some feedback to make it better. Can anybody help me? 👀 🔥

So for context, before yesterday, "everything was golden" so to speak. No abnormalities like I'm experiencing right now, to the point where I'm not running Youtube on Firefox ever again.

Like many here, Youtube suddenly started hammering my PC resources yesterday, and again today, for no known reason. I did the investigative things people do to find out the "why" and it seems to come down to uBlock Origin. Again, before yesterday, Youtube had no problems with this.

I've taken other measures like modifying settings in the about:config and such, but only what has been recommended on a search. I'm not very familiar with that side of things. This treatment feels like it's done precisely jack.

So my disk usage starts going off the charts, and I'm still not sure where the data is being put on my system, only that my C:\ has used up an additional 14gb of space in one day for no known reason. The RAM usage goes up by about 20-25% but the CPU is being hammered, lagging the system out and being unresponsive in Youtube.

This has gotten so bad now that I've stopped using Youtube on Firefox (as mentioned) and only use it on Chrome instead. I use a similar ad blocker on there and there's no such issues, even though uBlock Origin isn't supported on Chrome.

Do we know why Youtube suddenly went totally batty yesterday on my system, and the possible cause (besides uBlock Origin)?

Is it just me, or is it no longer possible to select the "Image of the Day" as a background?

As you can see in this screen record, I am using the latest Firefox for Android and the tabs are staying loaded. I am using it on Hyper OS beta, Android 17 ...

This was indeed a very bad bug.

Nothing. Zilch. Can't open youtube, reddit, facebook, can't even open Google or DuckDuckGo. Just an eternal loading limbo that never even leaves the homepage. I know the issue isn't my internet, as all other applications on my computer that use Wi-Fi like discord and email tab are worling completely fine. Firefox Mobile wotking fine too (posting this from my phone). Anyone else run into this + have any idea on how to fix it?

what is this thing?

it suddenly appeared and i cant even select it.

it shows up on the "tab" spot.

anyone knows?

I've been using Firefox on Android for my Samsung Galaxy S25 Ultra (Mainly because I use a Lichess extension and I can only get it for Firefox) and I woke up today and my bookmarks button isn't on the bottom tab, nor will it let me add it in settings. Is this a bug or something? I can't figure out how to fix it

I have configured Firefox to always ask whether to open or save a file and it does. When I click on a file on a website it opens a little popup and asks if I want to save or open the file.

But when I select 'Open with Firefox' and click Ok it will then open the file and ALSO automatically download it and permanently save it to my computer. Why? If I wanted it saved I would have clicked on Save File not Open File.

I am aware that it needs to download the data in order to display it but this seems like it should just go into a temporary cache that deletes itself when I close Firefox or shut down the computer.

I find this to be quite annoying because it clogs up my download folder with junk files I neither want nor need in there. And whenever I want to actually download and save a file I then have to dig it out between dozens of useless junk files that never should have been there in the first place.

Why is it set up to work like this and Is there any way to change this behaviour?

I have enjoyed firefox forever. I have never even had issue with google...until recently.

That silly AI assistant thing is always at the top of the results, and man does it like to make stuff up. I have not yet had an interaction with it that resulted in anything but me trying to untie the web of crap it created.

Please tell me there is a way to just get rid of that prompt completely. I know i can just ignore it, but its so consistantly bad that i want it gone.

Halp.

Check it here: https://addons.mozilla.org/en-US/firefox/addon/profile-picture-viewer-hd/

Usage: Open a profile page, right-click the profile picture and select “Open Full-Size Profile Picture”

That's a weird one...
So far I only noticed it on https://www.hattrick.org (Firefox 158.0.1). When I start a Docker (4.84.0) container and visit this site I get this request (see image) triggered on almost each URI. It doesn't trigger when there's no running containers or in the private mode so I'm guessing one of the site's external trackers (probably blocked in private mode) is messing with localhost or 127.0.0.1 or any docker address in the hosts file:

kubernetes.docker.internal
host.docker.internal
gateway.docker.internal

Isn't this a security concern that some trackers on some websites visited with Firefox are allowed to get access to user's device through docker containers?

It doesn't trigger with Chrome or Edge.

sorry if this ask. i notice some menu things are not all there. they have some items listed and then a down pointed bracket thing.

how do i get all the menu to appear.

All of a sudden today Google search results started to show up like this.Centered for some reason instead of how it usually is to the left.
It doesn't happen in incognito or other browsers.
Is there a way to make google search result go back to the left?

UPDATE:Ok it seems to happen only when I'm logged in my google account.
I dunno why it's happening all of a sudden though as this only started to happen today.

Im talking about firefox for ios. Whenever i leave the app like just swipe up and leave or completely close i am being returned to a different tab than i used to be on. Sometimes it opens up the same tab for a while but almost every time im on a different tab. How can i fix this ?

I posted this into the Firefoxaddon subreddit but I didn't get any answers, so I'll try here.

Since JDownloader has become very unreliable when it comes to Youtube downloads (often get "File not found" errors, even though the videos can be played in browser), I've been using the FF addon "Easy Youtube Video Downloader Express". Now I want to download a long video, which would come to about 8.8 GB, so the download needs almost 18GB to download everything before processing it, but Firefox only gives the extension 10 GB of temporary storage.

Is there a way to increase that space? I've found no option in the extension options
