Firefox Community Forum

I'm on Developer Edition of Firefox. In previous versions of Firefox (Probably 132), I could share the window just fine, but since an update to either Teams or Firefox, it just results in a blank screen for viewers.

When a tab is opened or moved into a new window (image 2.png), the additional windows will disappear from the Windows taskbar after a few moments (image 3.png) and cannot be accessed via Alt+Tab, the only way to reach that window is via dragging the windows around or with the Firefox View tab.

I'm attempting to set up sync between my windows laptop and my new android phone. The phone has firefox loaded, allows me to pull up the 'sync and save your data' page, allows me to choose 'ready to scan' and presumably successfully scans the QR code displayed on the laptop (the laptop prompts me to approve the new device). Then the laptop indicates I need to wait to approve it on my phone, and the whole process stalls. The phone continues to display the mostly blank white screen with only the "moz://a" at the top and the spinning blue circle in the center. Eventually the whole thing seems to time out and I receive an error message on the laptop saying "websocket unexpectedly closed" and "device pairing failed".

My two hypotheses are that either still having my old phone (which is being retired to at-home use only, and I'd rather not de-sync) still synced is somehow interfering (seems unlikely), or that something about the new phone's software is interfering in the sync (seems unlikely and way out of my league in terms of troubleshooting around).

Help please?

When I attempt to use Firefox autofill for address/credit card/etc, Linux will prompt for Root password. After entering root password, everything freezes. I have no access to mouse or keyboard and my entire OS become unresponsive. Besides the hangup, my firefox tabs randomly crash as well with the following bug tag: https://crash-stats.mozilla.org/report/index/3020d645-af46-4821-bbfc-e4d680250213. I don't know if the two are related, but both eventually lead my my OS freezing with only hard power down. Every time I try to use autofill, it freezes my OS. I can keep replicating the issue.

Specs:

Linux Mint 21.3 x86_64

Kernal 6.12.13-x64v3-xanmod1

Cinnamon 6.0.4

CPU: AMD Ryzen 5 3600X

GPU: AMD ATI Radeon RX 5600

RAM: TridentZ Neo 64GB

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

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.

Hi there, I just got a new work laptop and tried to sync my firefox browsers so I could keep my passwords and bookmarks from my old laptop. Unfortunately I forgot my password, so I had to reset it on my new device. I logged in again on my old laptop but it's still not syncing or updating the bookmarks on the new laptop. Is there any way to move my bookmarks and passwords over to my new laptop? Thanks!

For weeks now google translate has not been working as it should, when I translate something it usually defaults to translating it to English, but if I change the language to any other than English it still only shows the English translation (or whatever language it got "stuck" on).

I have signed out and in of my google account, have the latest version of Firefox (134.0.2), refreshing the pages doesn't help. I don't have this issue in other browsers.

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew

After using the "recent browsing" menu in the top left corner of FF and opening certain websites from the "import tabs from other devices" menu it has completely broken a handful of websites on my PC entirely, even using other browsers.

The page will load but no content is displayed, no links or media, just a blank white page. This is consistent among these websites even among other browsers including Chrome and Edge.

I have uninstalled and reinstalled FF multiple times, cleared cache/history, hard PC resets, refreshed FF, Uninstalled and reinstalled every browser. The issue persists.

These websites still function perfectly fine on mobile FF and Chrome. I've exhausted website permissions, app permissions, etc. The issue still persists. These websites were functioning just minutes before I tried importing them from the other devices tabs. Something about that functionality has completely broken them on my PC.

This issue just appeared. Video will not play in Firefox. Windows10 PC, up to date with latest versions, as is Firefox. There is no error message or code. Just the spinning wheel. I see other people are having the same issue but I haven't seen a solution. Any ideas or help appreciated.

I think that I have already set up my browser with Mozilla but you still ask me to do it????????? How do I know it is done and if it is not done then how do I do it???????????

A video of what is happening . This only happens when I search something up, for example, if I search more than one thing up on Pinterest, Google and sometimes Youtube . . . I'm sure it's not related to any extensions, the only one I installed recently was Privacy Possum, but after noticing this issue I deleted it and it didn't resolve the issue.

Help me Please it's Killing my Eyes

I just installed Linux Mint. I am new to Linux. Firefox came with it. In the Firefox help/about, I see that updates have been disabled by your organization. I am just a single user. There should bot be any enterprise policy applicable. Why did I get this and how to get rid of it?

Any help appreciated.

I have no idea why my browsing history, open tabs etc. didn't reopen after this restart. I previously had all the settings correct to reopen all windows after a restart, but now there's not even a history available.

Hello, Thanks in advance for your help. I am having trouble logging into "trusted" web sites with Firefox and every update seems to add to my problem. By "trusted" web sites I mean sites like Charles Schwab, Spectrum and iCloud as well as my city's water department and my local hospital's portal. It doesn't matter whether I use "normal" Firefox or its privacy mode or safe mode-the problem persists. I am running Firefox version 134.0.2 but the problem goes back several months. I have Windows 10 and use Malwarebytes Browser Guard. The only other add on I use is Print Friendly & PDF. It doesn't matter whether these addons are running or not. The problem seems to involve either a loop, blank fields or very odd error messages. Some examples are below:

iCloud allows me to get to the point where it asks me to supply the 6 digit verification code. I enter the code and the site loads. Approximately 2 seconds later, before I can navigate to anything in iCloud, I am taken back to the log in screen to start over. The loops repeat as often as I want to try. Clearing cache and history does nothing. Since there is nothing abnormal (no error message or blank fields) I have not included a screen shot.

Spectrum allows me to enter my credentials waits a while and then gives me an odd error message about Feature Unavailable and suggests that I try logging in from home. I might add that all of these problems occur while I AM at home. Screen shot attached.

Charles Schwab allows me to get to the log in screen but the screen is unusable. There is a message that the session has timed out and I need to log in. The log in sections of the screen are blank which leads me to believe that the page is not loading all the way but that is a guess. Screen shot is attached.

I can log into all these pages with Edge (which I dislike using) with no problems at all.

I have Firefox set to automatically delete cookies and site data when closed. Privacy is set to Standard.

I would really appreciate any help that you can give me. Please note that the screen shots are BMP files that I had to rename to GIF files to get them to upload.

Thanks again,

Charley

Lately I've had to reload/refresh pages more frequently because of download issues. In order to the in FF I need to press the F5 key. To do the same thing in either Edge or Chrome all I need to do is right click and a little popup screen shows me the reload/refresh right there. Much more convenient to use. FF should use a similar technique.
