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

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.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.

My Firefox desktop app recently updated. After it updated, I now cannot access anything by right clicking. When I right click, a giant window of options shows up (see image). It doesn't change no matter what I click on. When I try to select something in the giant window of options, nothing happens. I'm having a very hard time with it, particularly because I can't open links into new tabs now.

PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

This error occurs constantly on Firefox. I've had to go to Chrome to connect. I want to use Firefox, but not if it keeps doing this.

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.

For some time now I have not been able to access any website secured with Captcha verification. My browser doesn't recognize that I'm a human and keeps going back to square one. Importantly: this problem does not occur in other browsers. However, I would prefer to stay with Mozilla, so it will be nice if something can be done with it. I didn't change any settings, I didn't change hardware, I didn't reinstall Mozilla, so that's not the problem. I've looked through my security settings and don't see anything that would help in this case. Especially since these are websites that I had previously accessed and logged in without any problems.

I always use the middle mouse button (pressing the scroll wheel) to open and close new tabs, but since the update, it doesn't work anymore and now types "=" if the cursor is in a text field. For context, I use an MX Master S3, mapped with Logi Options+.

Anyone else having this issue? How do I roll back to the previous version??

SOLVED: It was a bug with Logi Options+, not Firefox. When I hovered over the tab for the presets I had for CaptureOne, I noticed it also said Firefox. So seems something weird happened there. Deleted that preset and the issue in Firefox went away.

I couldn't find a way to delete this thread, though.

I accepted an update to my computer and immediately Firefox could not load, the exe file is missing. Again I use windows 7 . May have lost all passwords and bookmarks. Please advise.

Everyday I get pop ups usually for car parts, all for ICE cars and I have an EV these days . . . . . Please stop sending them. Is that possible? Regards, [edited email from community support forum]

My firefox automatically updated on January 14th. Since the update, it opens with the tool bar above/off the screen, the left side off the screen, and it doesn't allow me to scroll. If I go the the firefox icon at the bottom of the screen and click close window, I can sometimes get it to re-open normally and then leave it open for the balance of the day. I am running windows 11. My wife and I are have the same issue right after the update. Is there a fix on the way or a setting I can change to fix this.

Not as important but I want to get away from all things google. Right now my firefox is tied to a gmail account. To be void of google, do I need to completely take firefox off my computer and re-install with a new email account or can I transfer the account to a new email?

Appreciate your time Thanks so much for your help.

It's not that they are not in my Firefox downloads manager, which I expected. It's that I confirmed before closing my private browsing window that they were in my Downloads folder on my C drive, and when I went back after closing the private browsing window they were gone. Under "recent files" in my file browser it showed a couple of the most recent downloads and when I tried to click to open them it said they had been moved or deleted. Entering the first couple words of the file titles in the search bar in my file browser yields absolutely nothing.

This was over 30 files or so. It will be really irritating to try to find and download all of them again. Does anyone know of any way for me to get them back???

Installed Firefox on my laptop. Already running on my desktop.

Whenever I try to open a link, I get: Get an app to open this 'microsoft-edge' link

Your PC doesn't have an app that can open this link. Try looking for a compatible app in the Microsoft Store.

Is this Microsofts way of saying "Use Edge?" Can I change settings to make it work?

I am an academic. I use Canvas. When I am in Canvas and I try to open a document in it from Firefox, what I get are solid black pages. I do not have this problem with Canvas in Chrome or in Edge. I really don't want to use those Browsers. I actually have this problem with every PDF I try to open from all sites. This is a recent problem. But if I cannot correct it, I will have to use other Browsers.

ver: 134.0.1 Windows 10 Pro I have Firefox set to open filetype PDF in Browser. Normally I use IDM which automatically download PDFs, unless I press ALT key while clicking DOWNLOAD button, then it does not, in order to allow Firefox to handle the PDF.

Firefox presently does nothing. With filetype setting set to Open in Browser, Firefox Does nothing. If settings are set to Ask, it does not ask. The PDF filename appears at bottom of screen momentarily.

ver: 115.19.0esr Windows 7 Utl 7601 The exact same behaviour was also seen on a Windows 7 system running Firefox 115.19.0esr. PDF is also set there to "Open in Firefox". Again, when ALT pressed when clicking Download button, Firefox does nothing.

In current version of firefox when attempting to log in to yahoo.com I get the error message from AT&T:

Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over.

No error when using edge or chrome.

HOW DO I GET MICROSOFT OUT OF MY COMPUTER?

EXAMPLE: I NEVER SIGNED UP/IN FOR ONE DRIVE. IT MEANS THAT THINGS SUCH AS DOWNLOADS HAS A MICROSOFT TOOL IN THE FILE LOCATION.

HOW DO I QUICKLY FIND THINGS LIKE MOZ VPN TO DOWNLOADS? I RECEIVE VPN FOR FREE. IS THERE A SIGNIFICANT DIFFERENCE THAT JUSTIFIES THE COST OF FIREFOX'S VPN?

THANKS FOR THE HELP,
