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.

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.

I've uploaded my latest 2 crashes and hopefully someone can read it and let m know about anything, Thanks in advance!

hi, i genuinely have no idea why this is happening because it started crashing all of a sudden and it doesnt happen mid-use, i cant use it at all and restarting firefox just results in another crash and so on. what am i supposed to do??

Since the latest Firefox update, it has frozen the app & crashed my computer multiple times within a few days; it has also caused problems logging into my primary bank account ("access denied") but has nothing to do with the bank (I called the bank; no problems there, but they suggest using Chrome browser. NO WAY!) Every time Firefox has updated the past few months, it has interfered with my password vault’s proper functioning {Last Pass}. I am using a late 2012 Mac mini, running OS 10.15.1 (the newest acceptable OS for my computer). I attribute some of the problem to their adding a number of new features without making certain the basic app is stable.

Thought only Ubuntu's Linux Firefox 136.0 was 'unstable' on my Gateway E-475M laptop - crashes, restores session then freezes only to log me out, then completely locking up requiring holding down power button and rebooting...

Now, even Firefox 136.0 on WIN7 is crashing, then restores session only to go to the 'blue screen of death' requiring holding down the power button and rebooting...

Evidently, the problem is not with Ubuntu or WIN7, but either: Firefox (Linux or win version); or, the Gateway E-475M laptop (2.0GHz CPU, 4Gb RAM, 8Gb swapfile, Harddrive at 61% usage, Linux/Win on separate booting partitions, LAN + usb & pci wifi's, etc.) - both OS's used to work fine, but as upgrades to Firefox have come along, they have steadily gotten more and more unstable...

Sometime, I'm only making a bookmark, and it starts this circus act... does it on differing websites, etc. Firefox is the only thing loaded - using two windows on two different monitors ...at a loss as to what to do - Firefox is supposed to be THE lightest-weight browser out there, and was for awhile... the only extension used on both systems is "NoScript" - could that be causing the disturbance in the force?!?

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

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 ]

TODAY'S (NEW-ish) ISSUE: - Multiple times per day I Click the Yellow button Top Left Bar to shrink and put App in dock to open again later. When I re-Large FireFox shows EMPTY FireFox Bar like I "Quit". Each time need to go to History and RE-OPEN ALL TABS??????

1. 2 within THIS text box just now, I highlighted the words: "Today's Issue" and clicked BOLD - instead it added a 2nd set of parenthesis???? WTF?

Browser is open all day. Always multiple tabs open/signed in, Paid & non-paid Apps, Email boxes, Wix, etc, many website tabs up, I do a lot of "research" - to pay my $rent and/or live my life using this "tool". Is my typical behavior. IN THE MIDDLE OF DOING WORK - I need to fix re-load Firefox again and again. . . Interrupted, distracted, observe, deal with so many Tech failures every day from ALL brands, I am struggling to keep my "life" functioning.

470+ issues/articles counted in the 11 subject boxes - in HELP section. FOUR HUNDRED-SEVENTY.

Thank you to "Volunteers" responding to help / issues!! Do you do any MENTAL help volunteering? kc

I did a "dnf update" on my system yesterday which upgraded firefox from 137 to 138, however I don't think that is the issue because I downgraded back to 137 and removed the ~/.mozilla directory to create a new profile and I have the same issue. So this might be an issue with Fedora. When I started with a new profile after removing ~/.mozilla using either v137 or v138 when I get to the create a master password in settings firefox freezes and I have to kill it. Before downgrading and creating a new profile I first noticed the issue when I went to a site with a saved login and when I clicked on the password box to bring up the saved password firefox froze. Just accessing the password menu will cause it to freeze. Any help/pointers would be appreciated.

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.

As the title states, every time I try to zoom into a page using pinch and zoom with my touch-pad, firefox nightly crashes. However, if I try to zoom in using CTRL+ and CTRL-, it works just fine.

I have tried to disable hardware acceleration but it didnt help.

Any help or direction would be appreciated, Thanks!

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.
