I am unable to play any videos on firefox only because of this WidevindCDN crash messages. i have updated firefox to the latest version and restarted the device and tried again however this error keeps showing up and doesnt let any video play. Please fix

Firefox is running x 8 in my task manager at the moment. Why does it keep multiplying and slowing down my computer? I am almost ready to uninstall Firefox. If I merely need to revert to an earlier version of Firefox, please let me know how to do that. Thank you. Shannon

I've created 22 themes and in all of them the drop down menus such as "downloads", "history", "extensions", and "application menu", all became white instead of dark like they used to be. I really don't want to go through the process of fixing and reuploading them, I'd apprecate you looking into this and hopefully fixing it with a simple update. Please fix this problem, thank you!

Hi there, Last night I installed some new hardware into my PC, new motherboard and CPU for example. After that, I booted up the PC, everything worked completely fine and I was able to listen to Youtube / Twitch / Spotify etc. through Firefox.

This morning I boot up the PC, everything still works perfectly and I have audio coming from all other sources EXCEPT for Firefox. I have browsed every forum already but can not find anything that relates to me. I can't set my output device, since Firefox doesn't show up in the volume mixer. The tabs aren't muted. I have restarted Audiosrv and Windows Explorer several times. I have re-installed Firefox twice. I have tried booting it in safemode. All of the above hasn't resulted in a single second of audio. I am at a loss.

Kind regards, Siem Hoefnagels

Hello, I've got a reproduction issue on France TV live programs which I watch through nordvpn. The picture keeps "jumping" fast up and down in a very bothering way. This doesn't happen when the video is NOT live. I run the latest version of LINUX MINT. What can I do to fix it? The only way I found to stop the issue is to take down the resolution of the live video to its minimum which gives me a disastrous picture but stops the "jumping". I guess you might say there is something wrong with my GPU. The point is that my PC is brand new with an AMD 5600G, new MB, 16Gb of RAM and 500w of PSU. BUT more than anything I have to say that everything WORKS FINE with CHROME. I like FIREFOX I have been using it literally for decades now. (I'm 75). Is there a solution? Looking forward to hearing from you. Thanks in advance. François.

Hello,

How come that we are in 2023 and we still do not have major features like Chrome's Profiles or Orion Browser's Profiles.

For example, Orion Browser creates an app per profile and this allows MacOS users to customize each app with a different icon. This seems small but on a taskbar we can differentiate the instances faster.

Why is that the best option for managing profiles in Firefox is the Firefox Profile Switcher, a third-party tool supported by a community member?

Will this ever be addressed? Firefox is better than the others in so many things but, for example, even Safari implemented Profiles now.

To be clear: containers are NOT the same thing as profiles and profiles still have an usage. For example, my work profile has no syncs, different extensions and stricter configurations than my personal profile and this cannot be done with containers.

Thank you!

To identify myself I had to scan a qr code on a website using my phone. This used to work in firefox but it doesn't anymore. It still works in edge. I'm using firefox 119.0.1 x64 on windows 11 home 22H2. How can I fix this?

This morning the add-on 'Search By Image' has ceased working. I use it daily, it worked yesterday, and so far as I know there have been no updates to FF or SBI or Windows.

To test I tried removing SBI and re-adding it, and disabling Malwarebytes.

I disabled SBI and installed "Image Search Options". ISO works, though I prefer SBI.

Win11, FF is now 119.0, but it auto-updated when I went to check so I do not know what it was when the problem began this morning. I have not restarted, I have too many tabs open at the moment.

This is also happening to a different PC that is Win10/FF, but never had Malwarebytes installed. SBI still does not work after restarting FF v119.0 in Win10.

Any ideas on how to diagnose this?

my electronic health record is freezing using Firefox on 2 different computers in 2 different locations. Internet speed 45 mbps at 1 location and 900 mbps at another. Able to use it on chrome.

Was getting some crash reports....now have a black bar on top of new tabs...it finally scrolls when you are halfway down the page. any help would be appreciated.

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.

Hello. I am currently trying to play a web game, but something is very annoying. The game doesn't implement pointer lock, so I have to play fullscreen for the movement to be continuous. Unfortunately, every time my mouse passes past the top of the screen, Firefox automatically unhides the titlebar and controls, and over all tries to escape fullscreen mode. This is very bad for the game, as the mouse movements are frantic and need a continuous mouse. How can I disable this behavior, so that Firefox keeps everything hidden in fullscreen until F11 is pressed?

Recently have been unable to access the USPS Website from any of my Firefox Browsers. Firefox displays the following Message:
