My tabs crash all the time. Sometimes it'll go a while without crashing, other times it's literally every two seconds. Particularly if I'm doing anything that doesn't autosave. Thanks. Sometimes it's just whatever tab I'm on (or occasionally I'll click on one I've had open in the background only to discover it crashed at some point, other times (and not infrequently!) it crashes the entire browser. Sometimes when it does that, it also logs me out of everything for no particular reason as a little sadistic cherry on top. The passwords are still saved I'm just logged out of EVERYTHING. A few times, it seemed to have made my bookmarks go away, but force-stopping it and re-entering made them reappear, so they weren't deleted. I don't know what's going on but I'm at my wit's end. The crash reports mostly just say EXCEPTION_ACCESS_VIOLATION_WRITE (I haven't checked every single one individually since there's too many, but the ones I've clicked on all say that as far as I recall). If this keeps up I'm going to have to switch browsers or something because I'm actually losing it.

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?!?

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 ]

I get random crashes while streaming video (for example youtube). I am using a laptop with 2 GPUs (integrated AMD and dedicated Nvidia) and a secondary monitor. If the Firefox windows is on the laptop display I never get crashes but on the secondary display I get around 1-2/hour. Also, this only happens with hardware acceleration enabled in Firefox settings, if I deactivate it then the issue is gone. I think it runs on the AMD integrated graphics, based on what I see in task manager. I also have uBlock origin, haven't tried deactivating it yet. The crashses consist in a black screen from which I can only recorver by doing a hard reset.

Any suggestions on what to try?

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

Started a couple days ago

Youtube works fine for everything, except when i try to watch a video, the rectangle where the video is supposed to be appears black during loading (normal) but then vanish.

checking the console i get a huge error that's just unreadable for me

it doesn't happen on edge, or in private navigation

turning every addon off doesn't fix the issue, and it does it even in "troubleshoot mode"

i haven't "refreshed" because i don't know what kind of data will be lost when i do that

Hello, after the most recent Firefox update, and it doesn't happen with every web page but it seems to be most frequent on ones I have never visited, that I get a tab that says "Gah! Your tab just crashed". If I close the browser and reopen it, then reload the crashed tab from my recent History, it seems to work. Anyone else experiencing this (Win 10 Pro 64x desktop PC)?

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.

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

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

I wasn't sure what to select for the type of question so you can move it if you think another type would be better. I would have selected crashes but that isn't an option.

It happened again a few minutes ago while watching Star Trek First Contact. The Phoenix was about to go to warp and Firefox CTD with no crash reporter and when I looked in about:crashes there was no crash report. This exact situation happened twice while watching the movie Signal unknown or whatever the title is.

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

this is the latest crash report. had 19 crashes in about 1 hour. i have noticed when i put stress on my pc IE playing a game the crashes are less. i have 64g ram i9 14900k cpu. disabled all extenstions have uninstalled and reinstalled firefox but nothing im doing seems to help.

any help would be great.

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

While playing Free Games.org and Free Mahjong also on AOL Mail Firefox crashes after a few moments. I performed security scans and restarted, still crashing.

WHY CAN'T YOU FIX YOUR BUGGY BROWSERS??? LOOKS LIKE I'M GOING TO OPERA OR EDGE NOW!!! STOP C0000005 ERRORS! I CAN'T BELIEVE HOW YOU'VE MESSED UP A ONCE-GOOD BROWSER!
