When accessing the main search page my android phone is briefly loading an image of the Firefox logo that is all purple. It then starts loading the main search page. When I try to open a pinned site it is very slow and times out frequently. I'm concerned that I have a virus.

Hi Mozilla Support Team,

We are testing our commuter booking web application (carliftdubaitoabudhabiae.com) on Firefox for Android (v128+).

Our web app relies on real-time Geolocation APIs to show passengers their pickup points and Web Push Notifications for schedule updates. However, we are noticing a few technical issues specific to Firefox Mobile:

Geolocation Prompt Delay: When users open the booking map, the browser location permission prompt takes 4–5 seconds to load compared to Chrome.

PWA Service Worker Caching: After updating route schedules on the server, Firefox Mobile sometimes serves stale cached assets even after clear cache commands.

Are there specific Service Worker or Manifest configurations recommended for Firefox Mobile to ensure fast real-time location updates for transport web apps?

Thanks for any technical guidance!

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.

Since the last update 155.01 I can't use Firefox as it freezes and hangs after 3 - 10 seconds. On Windows 10 , 64 bit. There seems a bug with the last update for Windows 10 users

Crash report: https://crash-stats.mozilla.org/report/index/c0455e29-69e9-4030-8b03-fdf430260909

Not sure the crash report is related to the issue.

The same issue happens to all of my 3 Windows 10 PCs since the update from today.

I have uninstalled Firefox and downloaded again, but same issue happens again.

I cleared the cache also but to no avail

How can I use Firefox again?

Hello! Since the latest update to Firefox (153, I believe) my Firefox has not worked. It starts up perfectly fine, but quickly freezes, becomes non-responsive, and needs to be closed. No matter how many times I attempt to open it, the same thing occurs. There’s been been occasions where it hasn’t frozen immediately so I have been able to turn off hardware acceleration as well as remove my theme and disable all my add-ons/extensions, but this has done nothing. Creating a new profile does not help, nor does trying Safe Mode: the same thing happens no matter what. I tried to reinstall the update, but this also did nothing. I haven’t yet tried to uninstall & reinstall or do a Firefox refresh as those are my last resorts and I won’t do them unless I’m sure they’ll make a difference. I haven’t downloaded any new extensions recently, and this only started happening after the most recent update. I’m not sure what else I can try at this point, and am very frustrated.

starting about a month ago, my Firefox browser has become very slow. Sometimes now when I click a link (this happens about every 4-5 links) the spinning wheel of death appears and the browser doesn't respond. I have to force-quit

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.

Hello

I have Firefox 154.0 on my 2 PCs that have Windows 11 and both computers are updated fully as of 22nd August 2026 with both Windows updates and Nvidia drivers.

Background: On my 2 PCs I have an "old" stationary PC with Geforce 1070 TI card, and I have a laptop Asus Vivobook 15 PRO with a Geforce GTX 4600 card. Both computers working fine and no issues so far.

Symptoms: I updated Firefox. Note! I always update Firefox on my computers, so it wasn't a clean install of the browser. And suddenly on both computers there were black artifacts all over screen and flickering when scrolling on Facebook or Youtube. Also even worse on sites were you drag a div and the browser turns into a 1-bit disco.

Workaround that seems to be working for me: I went to about:settings and searched for hardware on my laptop (the one with 4600 card) and searched for "hardware". Then I disabled the hardware acceleration thing, or whatever it was, but unchecking the result after search. Then I restarted my laptop not using hardware acceleration and it worked fine.

Then again I search about:settings for hardware and checked the bottom of the 2, not sure what the first one was. And restarted computer.

Now I don't have those black artifacts and flickering any more.

Not sure if that somehow triggered something that works for fresh installs or not.

Anyway... I can't submit a ticket since I can't reproduce the error it's no point submitting to Bugzilla. But hopefully this makes sense anyways... But I'm pretty sure you guys are aware of this issue already. But posting anyways in case it might help.

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?

Every time I search for something my letters are duplicating weirdly, like "test" becomes "testes"?? Ive updated the app, cleared cache, switched keyboards, no fix. It only happens with the first word or two of the sentence, and it's getting really annoying especially when I need to make a quick search. More examples are " what" becoming "whatat" or "how to" becoming "how toto"

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.

So every time I use the iOS app, whenever I leave the app for a few seconds to look at another app, once I come back it always redirects me to the home page. It’ll never bring me back to the page I was just on. It’s a little infuriating because it happens 9 times out of 10. If this bug were to be fixed, I would really appreciate it.

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
