Support I am having problems accessing my accounts on certain web sites, I can access them with other browsers, just not Mozilla Firefox. The two main sites are: https://www.bigfishgames.com https://www.spectrum.net How do I solve this problem? Firefox has been my default Browser for two decades now, but if this problem continues it will not remain as the default. Michael

See attached screenshot. It just randomly happens from time to time, and I can't figure out what's causing it. I've used both Chrome and Firefox with the same results. Help!

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.

I have searched Support, enabled media Autoplay for all sites, Page Info for individual sites. Videos play but never with audio. Currently using FF 134.0 (64-bit) on Debian 12, but recall some problems starting about the 133.0 update. No audio with Youtube, Amazon testimonials/reviews, etc.

Please help?

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.

I'm not sure if this is a FireFox issue or a google glitch, but here goes. Please give me direction on how to correct the above mentioned problems.

Thanks in advance for your time.

I cannot do online banking with the Bank of Montreal using Firefox. A website (https://thebao.ca) does not display properly when accessed with Firefox.

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.

I was using DuckDuckGo and it failed a connection, now trying to switch to Firefox as my browser. I still get confused about browsers and search engines, but I want to be able to connect to a website that did not function with DuckDuckGo, all of a sudden and for no reason I could figure out. I have Microsoft 365 Windows 11 (I think) on 1 laptop and Windows 10 on another laptop; I am trying to use the newer laptop with Windows 11 but not totally switched over.

Hi, I'm having some issues with Firefox. I'm opening a website (which I usually visit) even slower than with Tor at the same time. I'd love to know why and how to fix it.

For the last day I've been having a problem with FF slow to load. I've tried the troubleshoot mode with little change. When it does load I can have problems with certain web sites loading e.g. Youtube, MSNBC, AOL mail etc. It's never consistent. The cache is clean and I've saved all the relevant cookies, I checked my internet provider and they are having no problems and I don't seem to be having any internal hdw issues e.g. ethernet cable connections etc. I reinstalled FF-not a clean install and seemed to help for a time. Do I have any options other than a refresh? I don't seem to be having the same issues with Edge or Chrome. All W11 updates are current. I look forward to anyone's comments.

When I am on Facebook and I am viewing photos and I attempt to enlarge them for better viewing all i get is a black screen. I was not having this problem before. If I change browsers to Google Chrome or MSN I do not have this issue. I prefer to use Firefox as my default browser, I have not changed any settings that would affect this so I am not sure why this is happening only on Firefox!. Please assist. Thanks in advance.

All of a sudden, I get a "Not enough room to save" error message when I try to download a fill. There is plenty of room on my disk.

Also, it's not giving me the option of just opening the file.

I've been needing to use Edge to download files.

On approximately Jan 15th 2025, I was blocked from accessing my internet provider's website/my account.

I have worked with their techs on two occasions to resolve any possible issues on their end. We have determined that the problem is with Firefox/Mozilla's security, as they show no blocks on their end.

We tried with a new account, new passwords, but are still blocked. Please advise. I have enclosed a screen shot of what happens when logging in.

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.

There's a bug with Firefox 134.0.2. where I keep getting logged out of certain websites, even without clearing my cache.

Is there a possible fix in the works for this issue?
