My browser started crashing after the latest update, and it still crashes even in Safe Mode. It doesn’t close immediately upon opening; instead, it shuts down suddenly after about one minute or longer. This issue never occurred before and only started appearing after the recent update. My system is Windows 11, with the following detailed information: Edition: Windows 11 Pro Version: 23H2 Install date: September 17, 2023 OS build: 22631.5624 Experience: Windows Feature Experience Pack 1000.22700.1106.0

Following my traumatic brain injury I do have a reading disability search that perusing your articles could take me up to a week.

As you see I am running Windows 10 on a laptop which Microsoft said I was good for another year using this OS. Your latest download executed and after 2 reboots continuously crashes after trying to view any of the five windows a browser I had open with multiple tabs in each.

Since the 152.0 update I've experienced near nonstop browser crashing, it crashed twice as I was trying to type up and submit this message,

Is this a known issue or solely on my end? running 64 bit, windows 10

You updated your browser on my pc today. Now I can’t open it. It opens but has not opened any sites. I’ve had to use bing. I’ve used your browser for several years but unfortunately I’ve not been able to. It locks up when I try to open YouTube. The blue circle starts and locks up. Too bad.

I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

for years now I have had this issue when browsing. It is so annoying. I have tried all the suggested troubleshooting. I deleted all extensions. This helped for a while, but not for long. Now it's so tedious to browse that I am thinking of getting rid of Firefox. It has just become unusable and no one can seem to fix it. I am using Windows 10 and no extensions. It often happens when I first open a page and while the page is being pulled up.

Firefox just updated to 152 this evening on my Windows 11 Pro system. It seems slow compared to prior versions. Also , every time you log out , it crashes and activates crashreporter which files the report. Any clues? Nothing changed on the system except for Firefox.

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

I cannot use Firefox without it blowing up my memory to 86GB used in Activity Monitor. I've cleared my cache, closed all my tabs and bookmarked them. I have a Macbook Air M1 2020. I've tried restarting and am definitely using the current version of Firefox. I also updated to the latest OS Tahoe 26.5 to see if that helped. What should I do next please?!

Every time I run Firefox 152.0b10 on Macos Tahoe 26.5.1 Mini it flickers and crashes. Its reporting a webrender compositor error. I made a new installation and it worked but I will have lost all my extensive userChrome/Content customization, as well as hours of time today and more hours to come transferring across and doing things like typing this out and checking versions.

And it flickers awfully on the new installation so is unusable. What should I do? I'm typing this on my Macbook Pro with M3 Pro & Macos Sequoia 15.2, which is not running Tahoe as it bricks all the Adobe software on the laptop. I refuse to rent Photoshop and Premiere for the exhorbitant price Adobe charge, and am transitioning to DaVinci products but not yet done learning.

I have cleared all caches, reset all the hardware acceleration stuff to off or force-disabled, and done everything else suggested by any and every AI agent, like switch off Widevine for a bit then on, or stop UBlock0 running in any way, shape or form. Things change when such things are done but don't work.

As I write I am seriously considering walking away from using Firefox and advising all my friends to not use it.

Every time a programme does a update on my desktop, which is several times a week, it crashes Firefox and I get endless messages all day to keep rebooting Firefox.

It is getting extremely aggravating, frustrating and making me very annoyed.

This is supposed to be a modern browser with no big issues, supposedly easier to use than others? not on my desktop it is not and has not been for several months.

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.

So for three days now, my firefox constantly crashes. I would be reading a story online or watching a video on Youtube and then it will suddenly freeze. In videos, it'll still play the sound but the screen will freeze. I can't pause or stop it. Then either Firefox crashes and closes or I have to close it for it to stop. Sometimes, when I try opening it again, it still won't open. I used to have 50 tabs open and never ad this issue. After this, I closed all the open tabs, even deactivated a bunch of extensions, run malware detection, and still the issue continues. I don't know what the problem is. I even followed instructions and deactivated hardware acceleration options in Performance. And I have all AI options turned off too. The app also recently was updated.

I had this trouble after Firefox's previous update, where the browser would just close as I was in a tab. It had stopped so I thought the problem was fixed. However, it just updated the browser a few days ago and again I'm having a problem where the browser will just close in the middle of me entering information. It does not have to do with which program I am in as it just seems to happen randomly. It does not save any information I've typed in.
