latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

Hi, so since around update 153.0 i've had this persistient issue of whenever I am forced to re-open firefox (whether by an update, a restart on my computer or a crash) it begins to persistiently quit responding and will never work until i close it. After a LONG while of just trying to open it again, it begins to run, but it also signs me out of a good handful of things, so I end up spending 20+ minutes signing in on everything (considering 2fa on some of those things). This used to just happen with the big number updates, but tonight my computer had to restart and I experienced the same thing happening with firefox just loading and loading. I tried letting it sit and of course it did nothing, I attempted to use troubleshoot mode and there was virtually no difference (it was still frozen until i closed it). The only things I haven't done are the nuclear options of refreshing or reinstalling firefox (mainly because I have a lot of extension settings I would rather not lose because I don't remember all of it). I am writing this on a mobile tablet right now because my computer is still experiencing this persistiently, no matter what i do now, and it's becoming annoying because of the fact that i do have to sign into everything EVERY TIME now it seems. Extra information about my settings to answer some of the "do you have (this setting) on?" or other functional questions: -I keep cookies on and stored on the device -I have hardware accelleration off -I had several extensions on including ublock origin, but again, troubleshoot mode (which disables all extensions temporarily) had the exact same result of firefox hanging. Disabling certain extensions manually also didn't work. -i can't provide exact technical info on my pc since im not on it rn nor really want to deal with fighting it any longer tonight to write this but my computer is on the lower-end, but can still run and does run things like discord/steam fine; firefox started persistiently freezing after a fresh restart of my computer, and I didn't open anything outside of firefox and related firefox modes (ie private browsing) attempting to troubleshoot today. -last time i signed back in before it kept crashing constantly was 4 days ago I really hope this explains my issue well enough and I hope someone can give some advice on my next step forward. I'm becoming a little desparate for answers since i don't know how long this goose chase of constantly re-logging into everything the services i'm logging back into will tolerate, as one of my emails is now blocking my main 2fa method for some reason, so I'm a little worried.

My hardware is low end from 2016, Pentium 3825U, HD Graphics, and 4gigs of RAM. In the old times, the browser was fast, but this year it has slowed down so bad. I needed to switch to Thorium browser because Firefox became so heavy, using too much RAM and CPU. Please make the browser light, fast, and good for old systems again! (I want to use Firefox back)

Current firefox version: 155.0

Since the last few updates, update frequency of title bar of inactive tabs slows down over time. Sometimes there is important info in title bar that should be updated frequently. Are there any flags in about:config that can be reverted to achieve that?

i have said many times that i keep getting Firefox running but not responding . i have contacted many places and complained had some of your r tech try and help now with the new update i am still getting it yet i was told it would be fixed. i have reinstalled i have removed and shut off some add ons cleared cache all but cookies and still i get it funny until the last 2 new versions i never had this problem it is a Firefox problem not mine. i would have thought you would have fixed it by now

i was just opening a page and it kept saying Firefox running but not responding and then i gt the photo i am showing you what is it and why see photo being downloaed by another insrtance ??

Since version 154, my 2017 Macbook Air running MacOS Monterey causes my fans to be always on. The battery preferences says "Using significant amount energy." I've turned off all AI features.

Why does Mozilla 154.0 always stall after a couple of minutes? It is a hell of a mess. I couldn't place this question without resorting to an older version of Firefox :-[[

Did anybody test V 154.0 anytime, at all?

I unfortunately updated a Windows 10 computer to this version of Firefox.

As such, I cannot provide you with troubleshooting information, because the new browser 154.0 does not work. At. All.

I did all the usual stuff like restarting the computer, the users of Windows OS junk are used to anyway. The Task Manager shows not less than 16 Firefox-processes, with a truckload of memory usage, having opened just one browser tab. Waiting for 20 minutes for firefox to show me the grace of continuing its operation didn't help either.

Any ideas?

i have been tired many things to do and have tried all of them instead of uninstalling and reinstalling Firefox. Which i should not have to do as none of what is happening is my fault. I have done all i was asked by many of you and have done it all . I am getting no answer and no real solution by Firefox to tell me why i continue to get that you all think i am a dumbie none of this is my problem yes i have desktop icons which i have always had and yes they ope up with Firefox and never ever have i had this before they have always open with no problem until this last updated version. I am constantly getting Firefox is running but not o responding. Why when i go to chrome or click the chrome add on in address bar a say click on my amazon I con it opens right up with not saying google is running but not responding. why ca none of you answer the question and why can it not be accepted that it is a Firefox problem and not me. As i have said i have had these same desktop shortcuts since i got my computer on windows 7. up until this last version i never ever had Firefox say it is running but not responding. Like ic said i have done all that way said by Bugzilla Firefox help and still no real answer and no fix . I am tellin you it is not me it is a Firefox problem. why can this not be researched and find out why. I am sure i am nt the only one with this problem. Please i need a solution or ill stop using Firefox which i have for over 20 years but apparently Firefox does not care and thanks SOLUTION PLEASE

I keep having problems with Firefox hanging or disconnecting. I have followed all the steps in the [Hanging] page, and I still have to shut it down and restart it often, sometimes as much as several times a day. I also frequently have to force quit the browser, or I get a message saying "Firefox is open, but not responding" when I try to restart it.

In support.mozilla.org/questions/1598971 it's still not clear how you're getting this. You seem to be posting this question from a perfectly running Firefox so it apparently starts up and works fine on its own.

It sounds it's related to your Windows desktop shortcuts, or their exact target perhaps — however without knowing their content (destination or commands run) there's not much more to do here.

If you have anything new to add to the questions in the thread above, please post in that original thread so anyone trying to help understands what this pertains to. WELL LIKE I SAID I HAVE HAD THE SAME DESKTOP ITEMS FOREVER EVEN BACK ON WINDOWS 7 AND THIS HAS ONLY HAPPENED ONCE WHEN I FIRST STARTED WITH FIREFOX AND WAS TOLD THEN HOW R TO STOP IT AND BY THE WAY IT IIS NOT A NORMAL STARTING FIREFOX I GET IT WHEN I CLICK ON TH S THDESKTOP ITEM THERE ASWELL HOW COME ALL THIESES YRS HAVE HAD THE SAME DESKTOP ICOND S AND THIS ONLY STARTED ON THE 154.0 AND STILL ON THA 154.1 AND NOT BEFORE AND ITS ME NO I THINK IT IS A FIREFOX ISSUE . i HAVE Y USE THGE SAME DESKTOP AND FIREFOX SESKT OP FOR YRS AND NOTHING AND NOW IT HAPPENS WHY IS IT ME AND NOT FIREFOX//

Firefox version: 153.0.4 / Windows 11 25H2 26200.9168

Attached are images showing the performance settings and the active extensions in case any of them proves to be responsible for the problem.

Yesterday I noticed a horizontal screen tear when scrolling down through sites like X(Twitter), YouTube, GMail, Reddit etc. I immediately checked my performance options and they were deselected. I activated them again, but this did not solve the problem, I also tried to active some layers in about:config but those were already activated. Checked Nvidia settings too, vsync is on, Edge is not affected, Chrome is not affected, even installed Waterfox to see if only Firefox-based browsers are affected, but that one was OK too.

Last resort was to refresh the Firefox installation from the uninstall utility. After the refresh and all settings/extensions got auto-reinstalled, the screen tear got fixed. I left the PC running over night and when I accessed Firefox again this morning, the screen tear problem was back. However, now, the performance options are disabled, and if I try to enable them and restart Firefox, the options get disabled again.

Would really appreciate it if anyone could provide a solution that does not involve refreshing Firefox daily.

Hello, For about two or three days now, when I launch Firefox and try to open any website, it takes maybe one minute to load the page, then the navigation is OK on every website.

It only happens when I launch Firefox for the first time of my session. If I close it then relaunch it, it's still very swift.

I tried clear cache and remove cookies, just lost my logins lol but didn't work. I also tried with no extensions, nothing changed. Lastly I tried to set "network.captive-portal-service.enabled" to "false" in "about:config" but it didn't change anything neither.

So before I try anything else that could erase something on my profile, I'd rather ask here for some help :)

PS: running FF 153.0.4 on Debian Trixie with Mozilla repos. Only have two extensions: µblockOrigin and NoScript.

Thank you in advance!

Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

Every thing will be working fine? And then I click on something, and it takes a long time. And then at the top of my prompt, it says Mozilla firefox is not responding. I've been dealing with this for some time now. You can't figure it out. This is happening on my computer. Also I would update it the program and the very next day.There's a prompt asking me to upload again. I upgrade, and then I still get the same thing.Mazilla is not responding.

i have checked my mouse settings and reset everything but no change,,this started after a windows update, so i went in and uninstalled the update but did not fix the problem..i don't know how better to explain it, the scroll just stopped working while trying to scroll web pages,when i try to scroll the page doesn't move ., if i move my pointer over to the right side where the indicator of where you have scrolled to is and i click under it to scroll down and sometimes it kindof goes crazy and scrolls through many,many pages instantly...i hope all this some sense to you computer gurus cause i have tried everything that i know...thanks for giving it a shot..i use firefox browser and windows 11
