Recently YouTube videos have stopped playing when I'm using the Firefox browser on Windows 10. This has occurred both on my laptop and on my desktop computer. The player, surrounding website, comments, description, etc. all load correctly. The video does not, instead displaying either the video's thumbnail and a buffering symbol, or a blank black screen and a buffering symbol. The time codes on the video load correctly. Ads do not play either, and instead after about 15-30 seconds of buffering the "skip ad" button appears in the lower right hand corner of the video. Videos play normally on both Chrome and Edge, and all other media content appears to load correctly (music/spotify, videos on social media websites, etc.)

So far I have tried: - Running Firefox in troubleshoot mode - Refreshing Firefox - Clearing the cache - Disabling and re-enabling hardware acceleration (didn't work either way) - Uninstalling and reinstalling Firefox - Rebooting my machine - Waiting for the problem to fix itself (it's been two weeks on my main desktop/tower and it's still not working).

At this point the only thing I haven't tried is messing with advanced config settings, and I'm avoiding that since I have no idea what any of them actually do (despite what certain reddit threads recommend).

As far as I'm aware, no specific update to either of my machines or Firefox has preceded the issue appearing. It's been going on on my desktop computer for about two weeks, the problem just started on my laptop last night.

It's worth nothing that I usually use UBlock Origin, Simple Tab Groups, and Facebook container. Those extensions are not currently installed since I had to reset my browser in the process of trying to fix the issue.

I can also confirm it's not an internet issue; speed tests show normal download/upload speeds for my wifi, and those have not varied since the issue began. All of my drivers are also currently up to date.

This web site ' cornerstonegrp.securecafe.com/residentservices/carolina-club/userlogin.aspx'. The site tells me that password or pass code incorrect. In the past allowed me to continue to the main web page. At this time all of the add-ons are disabled. Cornerstone web site is the only site not recognizing login. Please help.

After the last update to Firefox on my Mac Book Pro running Mac-OS Monterey, I was offered an update to Ad Block Plus. This add-on, AdBlocker Ultimate shows as installed but it won't run at all and shows as disabled and my existing AdBlock Plus quits working. I'm using Adblock Plus on my windows based computers with all synced together with the Mac Book and the Windows computers are OK, but not the Mac Book. Is there any way to get my Mac Book working correctly? In addition the last update to Firefox on the Mac Book opens by offering me "Life in Color" every time it starts up. How long do I have to tell it I'm not interested? Thanks for your help.

Ok, as it says above, Firefox is randomly shutting itself off, as if you were 'Exit'-ing. I have followed all the aspects of the troubleshooting webpage - so far, when in Troubleshooting Mode, it stays up. I have turned all add-ons, extensions, hardware acceleration...before I went to Troubleshooting Mode...to try and isolate what might be causing it - no luck. I can have as few as 4 tabs open or as much as 10-it still turns off. Now, this does not happen each and every day, but it's close. The last crash report sent in was dated November 11, 4 in total. I have the crash report ID numbers if needed. I can't create the scenario; it's acting as if I am closing the browser, which I am not. This has me lost and frustrated.

Hello,

When my VPN client Private Internet Access drops its connection to the VPN server, all the tabs I have open in Firefox say they have crashed. I can restore the pages by simply refreshing, but it didn't used to be like this. This doesn't happen if I turn off wifi or manually disconnect the VPN, only if the VPN drops the connection. Very strange.

My environment: - Mac Mini M1 2020 8GB RAM, 256GB SSD - MacOS Monterey 12.0.1 - PIA MacOS client 3.1.2 (build 06767) - Firefox 94.0.2 (64-bit) -- ublock origin 1.39.0 -- greasemonkey 4.11

Hopefully you can reproduce and fix it.

I tried to watch Netflix on your browser but got the error message above with a statement along the lines that I needed to install the latest update of firefox.

"It means that the version of Mozilla Firefox you're using on your computer is no longer supported. Follow these steps to fix the problem."

I did update and restarted the browser and later my computer, the same message is appearing.

I had a similar problem last year when an auto update came through. After several suggestions didn't help I opted to reinstall a previous version and upgrade that. Now it's back again with the v94 update.

I've disabled ALL extensions. No help. Themes don't seem to make a difference. However, when I went to about:config and entered "toolkit.legacyUserProfileCustomizations.stylesheets" to make it true to allow chrome.css files to work it began immediately. Reset it to false and "X"s are back. Set config to TRUE and it screws up the "X"s. Again, all this is with all extensions off.

I hate the transparency of the tabs and menu bars so I need to set .css files. How else can I do it?

Opening up firefox last week am a message saying something was wrong/couldn't proceed (I don't remember the exact text). I tried to delete the message, but it just came back every time blocking opening firefox. I tried to restart it, but the same blocking message reappeared. I then uninstalled it and all my files disappeared, of course. I've today reinstalled it, but no history, etc.. How can I get my original web files back? Do you have a 30 day grace period where any file can be restored like the one Microsoft has? Can I get my webfiles back at all? Please help. tmr W10 64bit

Hello，somebody。 My firefox browser has collapsed 8 times from 2021/12/1. It is currently operating normally, but the number of collapse is too frequent, and the user experience is very poor. The latest Crash report ID：bp-fd4c7367-1346-4a10-a2cd-244ac0211202

Nascar for one, there is no error message, just a white space where the video should appear but does not. There is no error message. https://www.nascar.com/video/franchise/all-videos/sneak-peak-kevin-harvicks-car-stopping-burnout-on-broadway/ Clicking on another video, the caption changes, but still on video.

It plays fine in Chrome. I am using 94.0.2 I have tried unchecking hardware acceleration and use recommended settings.

Thanks Henry

I asked about this in a previous thread and never got a response from the escalation group.

I use my computer all day and keep several tabs open for ongoing use.

This is an example of what I see regarding Firefox's memory use. I do not open and close tabs often enough to have this make sense.

Please help! I cannot afford to have so much of my available memory blocked.

That ugly man in the browser won't let me enter websites or pages within the website ,like sweepstakes entries on Cabela's website for example. My numbers are [phone number]. Michael Lodsin When I open Firefox, there are 3 or 4 blue screens pop up to make excutible orders to my computer, I always click them off. but they we not always there. Is someone using my computer from afar, or worse tracking my keystrokes or monitoring me ?

There are several requests similar to mine, mostly about Windows 7 (i have windows 10). I made sure the "general settings" within Adobe were set to use Acrobat as default, and i set firefox options (as near as i could tell) to save my pdf's with Adobe acrobat also. However, ALL my files - both already saved and new pdf's - now are listed as filetype "Firefox HTML.pdf" and all have the html icon. For my husband's business, we have to fill out state forms in pdf and forward copies to them and to clients. My clients are frustrated and confused that they cannot recognize the pdf's i sent by the original icons, and some don't seem to understand how to open the "html" files i send them (most of our clients probably use other browsers: when they showed up as straight adobe files this was never a problem) I need to fix BOTH my stored pdf forms AND new fillable forms from the state as filename.pdf with the adobe icon. PLEASE!!

I am finding a web site that I have used for many years is suddenly not working as the login will not work. I have contacted the compmany whose website i use and they have taken me through steps that point to an issue with firefox. (I can get acces to the site with MS Edge). If firefox thinks there si a security issue I cannor find how to make teh site an exception.

I also see that firefox thinks my browser preferences are being managed by my organisation. In fact I am my organisation and dont recall having set up a policy for my company

Can you help pls

Thanks

In the last few days, I started having multiple web sites blocked with "SEC_ERROR_REVOKED_CERTIFICATE". They work fine with Google Chrome and Microsoft Edge, and I trust them. One example is http://www.wumb.org, a public radio station. I found nothing in Firefox Help to bypass this security flag and go to the page.

If there is a work-around, please make it show up when searching for SEC_ERROR_REVOKED_CERTIFICATE in Firefox Help. If there is no work-around, please add one. Otherwise, Firefox, my favorite browser, will quickly get a bad reputation.

Thanks,

Hello,

I have a new Cisco Webex Desk Camera that it's not working with Firefox (Flatpak on Fedora Silverblue 35).

lsusb: Bus 006 Device 004: ID 05a6:0023 Cisco Systems, Inc. Cisco Webex Desk Camera

https://mozilla.github.io/webrtc-landing/gum_test.html shows two cameras "Video Capture 4" and "Video Capture 5", none of them work, the page shows an error message: "AbortError: Starting videoinput failed".

The same website works in Chromium (also a Flatpak), which only sees "Video Capture 4 (05a6:0023)". "OBS Studio" is also able to use the camera. "Video Capture 5" is not available in Chromium and freezes the image in OBS Studio. I believe Video Capture 5 is the IR camera that is used in Windows Hello.

Would you be able to help me to get this camera supported, please?

Overnight, my the text size on my Firefox interface shrunk significantly. No other programs have changed, nor has the text inside the browser. How can I change this back to the original size, and how can I prevent this from happening again?
