Firefox Community Forum

Dear All and Mozilla Developer Team,

Since the recent updates of the Firefox the Browser Performance has become completely unsuable on Windows11 running machines. Now after tracking the browser behavior I can assure that it is the Browser and not only the entire firefox crashes daily and hourly, but also the performance has downgraded dramatically.

There is also issue with the audio and video playback, which does not come back when the video and audio playback and popups are being blcoked and then unblocked.

What I dont understand is, why the update is being pushed into püroduction when and causing millions of users to not be able to work !!!! This is completely unacceptable. Is there any test done beforehand? Who has decided that this updates must be added to MozillaQ!!!!!

how to get back to the working browser? thanks in advance for information

the latest update 136.0.3 is broken. When right-clicking an item, none of the choices work (e.g. right-clicking on any word brings up a menu with 'open in new tab' as a choice, but nothing happens)

I click to open a NEW TAB and it does not work. I just updated to the latest version of FF now nothing happens.

The right click menu shows way too many options unlike before  and I have to scroll to the top to see the open in new tab. DOES NOT OPEN ANYTHING.

Am not being hyperbole but I swear to God I love Firefox more than anything. Okay, let's get to the main topic. I have a problem with Firefox on my pc, whenever I open Firefox one of my CPU thread is dying and its causes brutally lags. I know I have a potato rig but at least fix this browser as smooth as before. After I having a problem with dying threads whenever I open a tab and going to a website I desire it took so long isgt. I thought my pc was the problem one and I think "Ah I should upgrade my pc, but I still in debt" and it turns out the Firefox was the main problem.

Please Firefox fix this for me, don't suffer me more. I'm migrating to Chrome for a while cuz the Chrome didn't kill my CPU thread (I tested it for almost 2 weeks).

I attached you images from time to time, hope you could understand it! ;)

Win11 computer, firefox 136.0.3. Been using FF/Paypal for years, not working for a couple weeks. Click on vendor paypal link either does nothing or produces window with spinning icon which eventually disappears (image). Have tried everything I know of: safe mode, delete history/cookies, test profile, disabled ublock on paypal and vendor site. Can log in normally to Paypal acct. Paypal works on Chrome. Suggestions?

WHEN I open Firefox,Mozilla comes up with numerous tabs:Mozilla accounts twice. Settings comes up once. Get Support Moziila twice. 2 new tabs. does not display the scroll correctly on X.com. I get a prompt to add it to my I phone. I DID NOT Sign up for that because my account is blocked on my Phone.Essential add ons would not work. You added data from Windows10# Numbered list item

Some Firefox option is adblocking some links in Publishers Clearing House emails. The same emails work OK in Safari. There are no adblockers (now or ever installed) on this Mac. It's not the end of the world for me but it should be fixed for possible future use.

When watching a YouTube Livestream/Premiere and wanting to get to the most real time/current point by fast forwarding it, seems to work fine at first but then when it goes back to normal speed after a moment the stream cuts back randomly making you behind the actual current live timestamp again which can be annoying.

I tried the troubleshooting mode but it was still happening, other browsers i tried didn't seem to have this issue. Also happens only for YouTube, other streaming websites like Twitch work fine.

As detected by Malwarebytes, it keeps blocking the site, quarantining the site, and the site in question is, mysearchengine.co. I do not know why this site keeps popping up, it's irritating. As such, I want a way to completely remove this weird search engine.

I updated yesterday to Windows 11. Following that update,I had a few difficulties getting Firefox up & running. It seems to be OK now except for the Firefox icon appearing twice on my taskbar when I switch on my computer. Is there an easy solution? I am not technically skilled. Thanks for any guidance.

Last two days rirefox has been continously freezing on my laptop it has been recently updated I'm using Ubuntu 24.04.2 LTS on a Dell Latitude 7370 with an Intel m7-6y7s x 4 16.0 GB ram firmware version 1.15.3 Linux 6.11.0-19-generac kernel version. I did not catch Firefox up date

I have a new macbook air running Sequoia 15.3.2, firefox is up to date, my battery which should technically last about 12 hours and I only get 5. Ran through everything with Apple and they said it is a Firefox issues. I don't have any extensions, add on etc. Thoughts?

Hi! Someday it's occured that i cant make a right click to Firefox on a Windows start panel - when i use right click the windows just... disappeares. What can i do to solve this problem? Check the screens The correct work of right click on the panel is shown on the screen "correct work" It works with all the apps, but a month ago i noticed that when i make a right click on Firefox on my start panel nothing happens, it just disapeares.

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2
