Recently the browser offered to refresh so I'm redoing all my settings, including disabling the fullscreen animation. I've went to the about:config and changed the necessary values to be "0 0" but the animation still persists. What can I do?

I am on Mac and have already tried quitting the browser after changing and reopening, but it doesn't work. I've also changed the settings to remove the fullscreen notification window (You are now in fullscreen...) and that removed without issue.

and its only on firefox, in chrome its normal.

any suggestions

Hello,

I'm currently using Consent-o-Matic to refuse cookies. The consequence is that the various web page never remember me, so I have to log-in again everytime I'm coming back on a web page after a few minutes.

Do you guys know an add-on that would allow me to refuse all the cookies, except the ones necessary for web pages to remember me ? That would be very helpful.

Thank you for your time !

So I have this for a while but recently I had to fill some form in firefox and had to go back and forth to another app and it started really make trouble for me. Like rendering the browser useless for filling forms by copying data from another app for example.

Whenever I open a page in firefox and minimize it to open something else, it doesn't keep the page loaded. When I go back to firefox it reload the page and I lose whatever I was looking/doing to it, like form filling.

I have a redmi note 9 (4/128GB) and did all the tricks for the stupid miui to not kill the process and it seems like it doesn't kill it now (autostart, battery saver disabled for firefox, locked in memory to avoid to auto clear memory etc). But firefox still can't keep the page loaded, it may keep it sometimes but like 1 out of 10 times and only if switch back in like 5 seconds or something.

I took a look around and I have seen this is not specific to my device and it is around as a bug since 2020 at least, but others have some success on making firefox to at least keep the current tab loaded.

But I got lost, so many threads are locked and I don't see what is the state of this bug. And I can't pinpoint down any workaround that actually works for me.

So any suggestion for workaround and if anyone have any idea if the bug is being worked on or something?

I love firefox but this is a big deal lately and I need it to work as the other browsers :(

I only have only 5 tabs open together with the one I'm writing this post with. 2 reddit tabs, 1 telegram web and a site which didn't load and the process manager.

I'm on Windows 11. If I load youtube on one tab the usage will go to literally 3.5gb or so(not kidding) with more than 2.5 or so gb being used by the gpu. What can I do for this? I have more than 10 extensions and they use no more than 300-400mb ever.

MS Edge with these tabs opened take less than 1gb but I really like firefox and want to keep using this instead of microsoft spyware:(

As the title if i press x and only x by itself while playing a browser game, it shuts the tab entirely, this is a problem because some browser games make use of the x key, I've tried searching but i get irrelevant results that don't resolve the issue, so i would like to know how to turn this feature off please.

Edit:this happens anytime i am not using a text field, not just during browser games, i still consider this a problem because its incredibly easy to accidentally close a tab

Hey, I bought a new M3 Macbook Air and Firefox runs great on it and plays non HDR videos really well without any issues when viewed on my laptop's screen, no problems there.

But when I connect to an external display and move firefox there, then YouTube videos in Firefox stutter hard with dropped frames all over the place, but it's not actually YouTube frames which are dropping. I checked "Stats for nerds" and I can't see any dropped frames on YouTube videos itself.

But the actual display is very choppy and virtually unwatchable. That been said, the problem goes away when I make the video fullscreen.

These things are leading me to believe that Firefox has some problems when showing videos in Windowed mode on an external display.

I tried Edge and Brave as alternatives and did not experience the same problems in those browsers, so it's definitely something to do with Firefox and Mac Window Manager maybe?

I am new to Mac after coming from a decade of Linux. I am not sure how to troubleshoot this, therefore any pointers would be of great help.

More information: I tried this with 2 different external displays.

One is a 1080p 100Hz monitor using USB C to HDMI dongle. This was without any resolution scaling.

Second attempt was with a 4k monitor connected directly via USB C. This was with resolution slightly scaled down between 1440p and 4k.

Sites like GitHub and YouTube use vague “dates” to describe when a commit was made/video was uploaded.

Instead of showing useful information (e.g. “Last changed 2024-04-01”) they show vague bullshit like “Last changed 2 months ago.”

This is even more egregious in GitHub’s case because they round up - so 1 month and 1 week ago is counted as 2 months.

Is there any Add-on that replaces this UX nonsense with actual dates? ISO 8601 is preferred if possible. 🙏

OK, with me knowing that Google tracks incognito data, does Firefox do this as well? Just a kind of random thought that I had.

Hey everyone. I’m using Firefox in Strick mode and using Brave’s search engine. I have containers setup and have my google account (I post to YouTube) in its own container. I was comparing search engines and used Brave, clicked on a few links then opened google. Google opened in its container, I typed in my search and the resulte showed the links that I clicked on under Braves engine as purple. Is Google still somehow tracking me? I thought between strickt mode and containers the cookies and tracking would be contained.

HI, could you help me please. I am using Firefox Nightly 126, and I wonder if there is a function or extension to extract text from images.

I'm losing my mind here.

I'm trying to load a simple xpi file I created from this walkthrough below using Android Firefox Nightly.

Things I've done so far

Tried different compression methods to make the zip/xpi
Set xpinstall.signatures.required to false
Set xpinstall.whitelist.required to false
Made sure add on has an ID

I'm losing my mind here because as far as I know there is no way to know why the xpi/zp file is just showing as grayed out and not installable?

Hello. My question is somewhat noobish. I want to disable the option to set an image you find on the internet in Firefox as a desktop background on Windows. How do I go about doing this? Thanks.

I made userstyles and scripts. But I want an extension that I have a dropdown where I choose what style+script I want to apply. How do I do this

Hi, when resizing the window in firefox or toggling fullscreen there is always a white flash (for a split second) for the part of the window that he has to "fill in". This is very distracting as I am using dark mode on my system. Is there any solution for this behaviour? If it would be possible to change the color from white to something darker, this would help a lot.

I'm on a latest Windows 10 22h2 machine. Firefox is also latest.

half window maximized to full window

full window switching to full screen

What the title says, basically. I want to see tabs open on my other devices whenever I open up firefox on my PC. I'm talking about this page:

https://i.imgur.com/dOjjnrk.png

I believe this is possible on mobile, and I know about the Firefox Tab button that shows all of this, but that's not what I really want. It would be great to eliminate any extra clicks by just pressing new tab and seeing all my other devices instantly.

I am not satisfied with google chrome..I installed firefox in android...I am satisfied with the results.. I also want like google chrome..Firefox doesn't have it...Don't know how to do??? Let me show you a picture (red)..Thank you..

I have had it enabled for almost a year now. Just cleared all storage as refresh profile is not available.

Curious before I re-enable it if people still consider worth while at this time.

I understand the feature is still not fully supported.

So I trying to slowly shift to Firefox I haven't got a chance to give it a proper try.

I started doing some CSS themes for it but struggled alot with start-page, It seems to me that only way to change Firefox start-page is to use a website for it. which I find really annoying. and just default look of Firefox start-page is blend I cant change wallpaper which is weird.

so is there way to make Firefox start-page less ugly?

In every other browser on the iPhone that I've tried (Safari, Chrome, Vivaldi, Orion, Edge), you can swipe on the toolbar to move between your currently open tabs, and usually you can keep swiping to open a new one. Is this not a feature in Firefox for iOS? I've gone through all the settings and I can't seem to find a way to turn it on. The confusing part is that my friends on Android say that they've had this feature in Firefox for a while, so it existing in one and not the other is weird!

Please let me know if there's a way to get this working, and if you work on the Firefox for iOS dev team, please consider adding it!

So I've just made a fabulous favicon for my website, but the bookmark still shows the old, rather unattractive, placeholder icon. Is there any way to update the icon?

Having to look at the old ugly icon all day is making me go mildly insane :)

Any help or ideas would be greatly appreciated, as my Google searches have not yielded any solutions

Behavior: Start Firefox > Make Firefox do something > INSANE LAG for a while > no lag for hours, It's fine.

It doesn't matter if it's vanilla Firefox, the Firefox flatpak or even Libre Wolf, whether there is a profile, or there is no profile, whether it's running regularly, or in Troubleshoot mode. (This is a fresh archBTW install with Sway. ) Disabling disk cache is not it.

Each time the lag is triggered the browser's generating over 3 gigs of reads & barely any writes. (the disk activity led is very active during this time)

I see nothing abnormal in the Journal, Firefox when started from the terminal shows no abnormal error messages. (and no, I tried it on Xorg as well, it's the same)

Please help, I really don't want to migrate to Brave! 😮‍💨

Firefox does not support playback of Matroska files, even when the codes of the tracks are Opus and VP8 or VP9 which Firefox does support playback of. See [Rethink] Support mkv|matroska|video/x-matroska in Firefox.

Chrome will prompt to download an .mkv file when navigating to the URL directly in the address bar, however will play the file in an HTMLMediaElement when directly setting the URL at the media element src.

As I see it there are two (2) options to support playback of Matroska files in both Firefox and Chrome, including media documents created when navigating directly to a Matroska file that contains codecs the given browser supports:

1. Transcode all files where the extension ends with .mkv to VP9 for video and Opus for audio in a WebM container using native ffmpeg or ffmpeg-wasm after intercepting the request using browser extension code.
2. Launch an external media player from the browser such as mpv to play mkv files; or embed a media player that supports playback of Matroska files in the browser.

Which approach would you employ?
