I need to reclaim space on my hard drive so I was looking for apps to remove. I noticed that I have two installs of FIrefox. One is listed as "Mozilla Firefox (x64 en-US) (261MB) (2/7/2026)"; in the description area (when you expand the app panel) it says "135.0"; the "Modify" button is grayed out - all I can do is click "uninstall". The other install is listed as "Mozilla Firefox 72.0.2 (x64 en-US) (188MB) (2/23/2024)"; in its description area is lists the version again "72.0.2"; the "Modify" button for it is also grayed out - I can only uninstall.

How do I tell, from the Firefox that I launch from my taskbar or start menu, which one I'm running and which install I can remove?

I'm on a Windows 10 Lenovo Flex 3 laptop.

I knew I shouldn't have did the 133 install.... I did a hard start up and wouldn't you know it, all my tabs are gone.... Gone where? And Why? Searching says that I should go to "session store-backups folder"

why in the hell should anyone have to go anywhere to do there own repair when the new updates should be working.....

There use to be within SETTINGS a click/link to restore previous tabs...Who's responsible for dropping that? I'm using 135 Version, and I knew I shouldn't have done the update, damn....I've got enough problems with Win 10 and Office and I don't need this aggravation.... Anyone who how to resolve this problem, and if so thanks!

Only some videos play without audio, only in Firefox

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works
vp9-vorbis-spring.webm      Works     Works       Works       Works
vp8-vorbis-sintel.webm      Works     Works       Works       Works
avc-aac-nerdist-friends.mp4 Works     MISSING     Works       Works
avc-aac-big-buck-bunny.m4v  Works     MISSING     Works       Works
avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works
audio-sample.opus   Works      Works
audio-sample.flac   Works      Works
audio-sample.wav    Works      Works
audio-sample.m4a    FAILS      Works
ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

There have been numerous sites which I have visited for years on Firefox but recently some have not been recognised. Today Firefox would not progress my sign in to Virgin Media. Brave is giving me total access to everything. I may have to abandon Firefox entirely. Can anyone suggest a work- around please?

I have run across threads with similar questions in both mozilla support and reddit, but as they are old and archived I cannot add additional info or request clarification, so here is (yet another) new one- I understand you can go into manage data in settings to delete what you want, however in mine it only shows a handful of most recent (opened today or currently open) since my settings clears history and deletes cookies upon exiting ff.

Cookies and Site Data section shows only 40.7mb of data is stored and in Manage Data only shows 8 sites... Clear Data area, with only these two boxes selected (attached) and 'everything' (time) still only around 50mb. My storage/default folder has 1005 folders and the data is over 1.5gb; I would like to manually delete all of this and as others have tried to ask, am wondering if this is ok to manually select them and delete in windows, or using windows %appdata%(?) and if so, will the sync feature (if I just clicked 'sync now') still retain all my bookmarks when I relaunch ff? Not concerned about any browsing/form history or passwords, only bookmarks.

Other than using VPN (which is too expensive for me at this scale), is there any way to set my computer so I can access maps without the "Gulf of America"? All I need is to appear to move 100 miles north to Canada.) I found MapQuest, good for directions, but would like the other features.

Can't believe Google rolled over so easily. Bing doesn't surprise me at all.

I’m currently using the latest version 135.0 (64-bit) of Firefox. Suddenly, the AWS console stopped loading completely. Even the help page linked at [https://support.mozilla.org/1/firefox.../firefox-help|page] is not loading.

I’ve noticed this error on the AWS console page:

I’ve also attempted to use the Troubleshooting mode, but unfortunately, that didn’t help either.

Have a client who's having a problem with his email links: apparently, clicking on them opens a magnifying window so he's required to right-click on links to open them. He mentioned that he double clicks on the links so not sure if that's what would trigger a magnifier, but it doesn't seem likely per my experience, rather, it would either open the link or highlight text. Let me know your thoughts.

Thanks!

I've noticed that HDR content on YouTube plays at apparently maximum brightness, which is overwhelming. The same video using Google Chrome behaves as expected. For example:

https://www.youtube.com/watch?v=Xod2xiLA9CM

I'm running FF v135.0 and Chrome v133.0.6943.54. When using Chrome, the video brightness matches system brightness settings on my Macbook Pro (running Sequoia 15.3) but when I use FF, the video itself is incredibly bright, as if the white levels have been maxed out. It seems to be a problem with handling the HDR content. Even stranger, it's as if the browser is able to increase my screen brightness itself, but only in the video pane. I doubt that's actually happening, but that's what appears to happen. If I switch to another tab and then back to the video, it takes a few seconds for the video pane to increase extreme levels.

Also, I tried to take a screenshot of it but the screenshot doesn't show the extreme bright levels that I see when I'm using the browser.
