I have two computers that I use at different times and for different reasons. I want the open tabs on them to be the same. I am signed in on both computers but there is no syncing happening, even when I go into the menu under my account. It says it's syncing, but it's not. When I try to "Add another device" the option of adding another computer is not given. I do not want to use the profile backup because I want to MERGE the two sets of open tabs between the computers, not overwrite one.

few days ago, i was trying to remove unimportant entries from the browsing history section. i discovered that my delete button wasn't working and no entry was being deleted, not even when i was trying to remove using the mouse right side button. at first, i thought the delete button of the keyboard has become faulty. but i found that it was working fine in other apps or parts of the Windows OS. so i tried again removing the entries but couldn't do it. then i closed the firefox browser and reopened it. to my horror, i found that all entries before November in the firefox history section have just disappeared. nothing is there. i felt very much shocked and sad because there were lots of important entries which i have stored for almost two years. now i don't know how to restore my lost history entries. just because of some errors in the firefox program, i have lost my long saved entries. please suggest me how to restore it.

This limitation prevents big games running on Firefox despite Firefox has the best performance on WASM. Will there be a proper way to change this limitation or plan to remove it?

Where possible I prefer to sign in using a passkey (stored on a USB key). I use a password manager for the rest, and have thus disabled password saving inside Firefox.

However, when password saving is disabled, Firefox will not prompt for using a passkey when inside a login field, this works when I re-enable password saving, but that leads to other annoyances.

Is there a way to enable passkey the passkey option without also enabling the password saving?

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, ye… (Lesen Sie mehr)

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.

Everytime i highlight a word and right click it to "search google for" it switches to that new tab. This only started happening for the past two weeks. I already changed browser.search.context.loadInBackground to true in the config.

Also noticed this does not happen in private mode, but it does happen in troubleshoot mode.

Is there any way to change that? Thanks

When will this issue be resolved?
