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?

Hi Mozilla team,

I’d like to report a serious issue with Firefox lately. The browser has been performing very poorly and frequently becomes “Not Responding.” In many cases, websites fail to load properly or get stuck indefinitely, even though my internet connection is working normally.

I’m experiencing these issues on the latest version of Windows 11 with the latest version of Firefox. This has become quite frustrating and significantly affects my daily browsing experience.

I hope the Firefox team can investigate these stability and website-loading issues and provide a fix soon. Firefox used to be much more reliable, but recently the overall experience has been very disappointing.

Thank you.

My Desktop - Win10, 260+ Gigs RAM/14+ TB HD space Firefox updated a couple of days ago, and again today (this time to 155.0.1) Ever since . . . . . . Having Major problems NOW No Rt-Clk function in Ff Ff menu buttons non-functional Ff tabs can no longer be rearranged Data entry fields, dropdowns, Submit buttons, & "add to cart" buttons not working on Ff pages -Things I've tried; I rebooted Ff & Windows several times each - No Joy I cleared Ff startup cache twice - No Joy HELP! I use Ffox for roughly 85% of my online activities - I'm pretty much hosed

PLEASE HELP!

Hi a few days ago I updated my firefox version 155.0 well I had 3 open tabs going back to and forth to different sites. when the update firefox popped up, I mistakenly hit update & a notice said firefox is attempting to save these sites, I closed the notice then shut down my laptop,

I never take a update with any thin running. when I turned on the w-10 lap top seem to take awhile to load, so I let it load, and then I shut it down completely. I went to task manager and my read write on my c: drive was running at 100% for about 15-20 minutes. I went to firefox settings and re-set "cache at startup"

This seemed to help some, but still not sure if it is locked in a loop, looking for those those saved files.

I am 80 now and not a pc savvy as I was. not sure what the normal time the c drive for read write should stay at 100% after starting my laptop, I know there is indexing going on, but I thought it would be done by now. after. Thank You Gary Kouri

Everytime I switch app and come back to the browser, my tab reloads. So like if I am watching a youtube video and I've watched it almost half, after the reload it starts over.

I've uBlock origin and Hide Shorts extension installed.

i have tried anew profile got a the newest version and it still does not help i guess the people doing the updates have no idea how to fix the issue or care none of you can really help all the idea you have had i have tried and still i get the same Firerfox running but not responding' guess you will force me to go to chrome instead which does not do this nor does Edge so you can not tell me it is not a firebox issue because neither Chrome or hedge with by the way all the same desktop icons i have had for years work

Whilst on various websites, reading articles or even on Gmail, Firefox takes me off them and takes me to Recent Browsing and I have to click on the website from there - this happens frequently.

I log in get a dead home window cannot delete , no response to cursor have to use task bar icon to overlay dead home screen. when return to home scree I get the dead old window and use task bar icon to get live home screen to continue. The dead home screen appears and have to select firefox from task bar each time.

Hi Mozilla Support Team,

I am experiencing severe browser lag and high CPU usage on Firefox specifically when managing complex backend forms and inventory management scripts on our e-commerce operations portal.

The page script execution freezes when opening multiple tabs alongside developer console tools. I have already cleared cache and disabled third-party extensions, but memory leaks still happen during heavy DOM rendering.

Is there a specific setting in about:config or hardware acceleration flag recommended for heavy web app environments?

Thanks!

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

This has been in the last month or so. It will freeze up and I can't break out of it. Last time it froze the whole computer and I had to power down and restart. There must be something that changed. And there must be some way for me to be able to quit when this happens. Last time it was on a video call with my 104 year old mother and it is very annoying. The whole thing froze and I had to restart the computer and when I got it back up, she was off. I need some way to break out so I don't have to do a complete restart. t.

Updated Firefox to 154. When I select Firefox, I get a notice that Firefox is already running. If I cancel, Firefox comes up but I quickly get a notice that Firefox is not responding. I tried refresh but that didn't fix it. If you don't have an answer, I'll de-install and then (maybe) reinstall. -JJM

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.

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.

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.
