Firefox (currently 157) continually crashes on my Windows 10 machine. Task Manager shows Firefox downloading sub apps (currently, 11) until memory is full. Then Firefox crashes. Task Manager shows 11 sub apps open right now using 537Mb of memory. I opened in troubleshoot mode. If I open in normal mode, more than 1Gb will be used with 14 or 15 sub apps downloaded. Only two tabs are shown as being opened. This started with one of the earlier updates and newer updates didn't fix the problem. Even emptying the cache didn't help. Do you recommend totally deleting Firefox and starting over from scratch?

Yesterday morning my Firefox was updated to version 157 and ever since it reopened it has crashed too many times to count. Sometimes it will run for 20-30 minutes, but then it will crash repeatedly in just a few moments or a few minutes after reporting the crash and restarting. I already tried reinstalling the current version with no success in solving the problem. I could not even keep it from crashing while trying to type this question, so I am now using MS Edge as my browser until I can find a fix for Firefox.

Mozilla Firefox keeps crashing repeatedly while I am searching or typing, and the problem persists. Why is this happening, and what is the solution? I request you to investigate and fix this crashing issue as soon as possible.

On Thursday 3rd September 2026 Firefox stopped working. I tried lots of things to get it to work to no avail. Today, 8th September 2026, I had already deleted the Firefox that was already on my PC so I downloaded a fresh copy from the Firefox website and installed it. It ran perfectly for about 30 minutes then I shut it down. 5 Minutes later, a Firefox crash report appeared which I duly sent of. Checking Event Manager a string of error messages saying the same thing, Its the XUL.DLL file that keep crashing! This was the same file that caused the failure last week. I had made sure that XUL.DLL was not on the pc when I downloaded Firefox today. When I click on the Firefox icon it open but stays on a black lower half of the screen and boxes at the top, white lined but black and transparent lines moving left to right across them, eventually it fails and closes, after a few minutes it send the crash report. Its a shame because I have used Firefox for many, many years and now having to use Edge!!!!

Every time I attempt to log into X.com the Firefox browser stops working entirely. Dead. Nothing. Won't open or function. Need to restart my computer to access and use Firefox. This does not happen when I use Chrome.

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.

I usually use firefox to download things, and watch videos, however, sometimes, when I change tabs, try to minimise firefox, close a pop up, even if I just pause a video, it randomly decides to instead completely freeze and require the app to be completely restarted, and it occasionally decides to roll back my search history.

In fact, Firefox crashed as I was writing this, i'm lucky my progress was saved, these issues have made firefox completely unusable about 70%-80% of the time, and i'm running out of browsers to switch to, opera is run on lies, chrome is just bad, and now firefox is dying.

Just for reference, no other application or web browser that has ever been on my current device has ever acted like this, I'm currently using a decent PC running Windows 10

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.

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.
