Firefox Support Forum

Hello, so when I watch youtube on FF my cpu usage goes up alot and the fans go nuts. I have a very capable i5, rtx3070 machine and this issue started just a couple of days ago. I have not done any changes or updates which could trigger this problem. The problem starts mainly when I Watch in full screen mode or have multiple non-fullscreen vids active. All other apps show no signs of problem. I can watch the exact same video in Edge, no fans/high cpu, VLC works fine, Chrome is OK, it's only in FF that the problem occurs.

I have tried the following: 1.Reinstalling FF 2. Activating HW acceleration in FF and forcing it in Windows11 3. Theatre mode is off and all other YT settings are off. 4. Updated Nvidia and windows 5. FF is the latest version. 6. Disabled all my addons/plugins

No clue what can cause this..

Hello,

The subtitles aren't appearing in the PiP pop out when the original video is Disney+, but they're working on Netflix, Amazon, and YouTube. Is there a way to fix this? I looked around in the settings and couldn't find anything.

Thanks!

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

I am trying to log into the forum. I am attaching two screen caps. The first is the log in screen. When I click on the continue button, i get the second screen.

Thank you

When I try and get a web page for example wordle or facebook I get following message 'There was an error displaying the search results. Please try again.' I have windows 11 on a laptop and am using duckduckgo as search engine. It has only started today and on Edge using same search engine I do not have the problem

Hi team,

I have syned my account to santhuusanthosh51@gmail.com like bookmarks passwords Etc., Today i have formatted laptop and reinstalled laptop and logged in with same same account it shows no data in it like history Bookmarks and password.

please help me to get it back.

I have installed the German language extension . I can go to a sight written in German and it translates fine . THE SECOND I USE ANY SUB MENU WITHIN THE SIGHT IT DOES NOT TRANSLATE . right clicking and "translate" does not work since "translate" does not exist on the tab .

The firefox translate feature only works on the initial screen !

I can find no setting to fix this

In release 126.0 (64-bit) in Windows, persist logs in developer tools is not working for me. I've tried selecting and deselecting all the combinations in both settings areas in the split console, quitting the browser in between. Is there a new place to set this?

Today while using firefox all my open tabs and windows crashed. Due to the situation, I had to restart my computer because everything was stuck. When it restarted I couldn't restore the previous session so I used various methods to restore it but I still can't restore the windows and tabs that were open today. I would like you to restore my session from before the failure today.

I just accidentally deleted my account and i just can't remember my password but i don't want to reset my password because my data could be deleted and i have no backups and no other way to get my account back besides resetting my password

I have restarted and updated both firefox and my computer and disabled all of my security extensions for Canvas. However I still do not have any content loading for assignments or quizzes.

Earlier I tried to open firefox to go on the net and Bing came up. I uninstalled Firefox and reinstalled and the same happened. Then I deleted the Firefox folder fron the hard drive and then reinstalled Firefox again. This time it opened correctly. I can only assume but don't know, the Bing thing came about through one on the windows 11 updates. How can I stop this from re-occuring or can I? I only ever use Firefox, its just the best, thank you.

PS: I did have Firefox as my default browser but Firefox still became Bing. Lis

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?
