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.

As creator of retroonline.net. We recently noticed Firefox have limited value size in IDB which Chrome and Edge do not have. 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?

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

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

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.

I'm keep receiving mails to verify my account, when I open the link, it redirects me to my Mozilla account but everything seems to be in order and y don't want my account to be deleted. How am I supposed yo verify it? I have Two-step authentication, the Account recovery key, a Secondary email and I even singed in several devices.

Thanks in advance for the help.

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?

There is a bug in Firefox Browser where it doesn't allow you to scroll up in the chat during the livestream and keep your place there to read a message. It auto scrolls down to the new messages everytime a new message appears in the chat.

Firefox is the ONLY browser that does this so it must be a bug. Chrome, Edge, Opera, Brave, etc none of these do this. It is especially problematic in livestreams with many viewers and an active chat, making it impossible to read a previous message if you want.

It happens on all platforms, twitch, kick, YouTube, Parti, Rumble, anything with a live chat

Since the 135 update, the pinned shortcuts on the new tab are now not centered under the search bar. I've found a temporary fix in about:config (see below) but this makes the icons incredibly small. I would just like the pinned shortcuts to be centered now instead of left adjacent.

When I navigate to youtube and try to watch a video, the player does not load. It just shows white in the space where the player should be. No video, no audio, no nothing. No matter what video I click, the same thing happens. The only workaround I have found is that if I go to a page with an embedded youtube video, and click the "watch on youtube" link that appears in it, it will load a youtube page that can play videos normally. I can use that page to navigate youtube and it will operate normally. However if I type in youtube.com or get to the site some other way, the issue happens where it is only white space. It is very frustrating.

What is the issue with Firefox and the True key password storage app from McAfee? I use Firefox to get away from Microsoft and Google and have for decades. But now the True Key app no longer works and Firefox states something about a violation of policy. I depend on bookmarks to go down the list and pay bills using the True Key app for logging me in. When will this issue be resolved?

When Family Tree asks me to login to Ancestry, I do and it comes up with a blank page that says Ancestry user has been authenticated. It doesn't come up with my Ancestry home page.
