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.

Hey, I've been experiencing my YouTube and Twitch tabs crashing almost every 20-40 minutes and it's been kind of annoying.

Does anyone know if the crashes are because of my drivers or Windows not being up to date? Never had this issue with Opera before.

When I open Firefox for the first time after logging in to my macbook, after a few minutes, a second Firefox icon appears in the dock at the bottom of the screen. Why is this happening (only started a few days ago)? And how do I stop it?

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000000a (0x0000000000000030, 0x0000000000000002, 0x0000000000000000, 0xfffff80274225392) CAUSE WAS FIREFOX.EXE

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

Hi,

At some point in the last couple of weeks, I've started running into very frequent crashes running Firefox in the Linux container on my Chromebook. It previously worked well, but is now unusable. I'm now running Firefox version 147.0.3 on Chrome version 144.0.7559.167. This is after I did a clean reinstall of Firefox using flatpak, which didn't help. It seems like it often happens when my mouse hovers over a browser tab or icon (eg account, extensions, hamburger). Other quirky display behaviour, which mayor may not related, is that videos are often not working (eg Youtube, BBC), and various browser windows (eg when selecting Manage Bookmarks, or restarting in safe mode), open a small size-reduced window. Latest crash reports below -

Thanks for any suggestions.

Trying to download updates from Intel.com and as soon as I click the download button, Firefox just locks up and won't allow me to do anything. I have to basically shut down firfox through task manager to get the browser to work again. I have 139.04 which is the latest update for Firefox

A message to Mozilla if this is a bug how about fixing the problems that some people are having instead of consintration on implementing AI into Firefox as I want a browser that doesn't and isn't link to AI as many other people do as well as some if not most of us are sick to ther back teeth with everything having AI installed with in the programs.

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000000a (0x0000000000000030, 0x0000000000000002, 0x0000000000000000, 0xfffff80274225392) CAUSE WAS FIREFOX.EXE

Since a few days, Firefox started crashing each time I receive a notification.

For example, with this notifications test website: https://www.bennish.net/web-notifications.html

Each time I click on the "Show" button to display a notification, Firefox becomes completely unresponsive: the content of the window is completely frozen and I can't click on anything. I must close it and restart it to make it work again. When I restart it, a dialog displays:

> Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

In both applications, the notification is never shown: the freeze occurs before.

I tried the following changes but they did not stop the issue from occuring:

- Deactivating hardware acceleration - Troubleshooting mode - Deactivating firefox notifications in Windows - Deactivating `alerts.useSystemBackend` and `alerts.useSystemBackend.windows.notificationserver.enabled` in `about:config`

At the same time, I noticed that Thunderbird (v144.0.1, 64bits) started having the same issue. It haappens each time I receive a new message in the background and a notification should appear. Maybe this is related?

Firefox crashes constantly when I load it mostly when in youtube though. I notice so I am not sure what is causing it to crash it could be ublock origin as I use that to block ads on youtube that is the only thing I can think of or maybe the return dislike button but here is my crash report below ID bp-8f27f4a1-7ed0-492e-823d-e57af0250304

Started using Netscape and been with Firefox ever since it started. For the last few months, I find that my Draytek 2866Lac router randomly crashes and resets itself when I am using Firefox. I cannot pin it down to opening any particular website but it seems to be related to opening a new tab / link. I have FF set to open new tab automatically and no extensions (other than British English) are in use. Using FF, I can seldom go more than 5 -6 hours between resets. Not using FF, I have now managed 2 days constant uptime on the router - which is a fantastic change! Is there something peculiar with my system and any ideas how I can get stability again please?

Just updated my MacBook Air to Sequoia 15.7.3. Since that update, Foxfire will open, but when trying to open an article in Foxfire, Foxfire locks up and doesn't wan to shut down even with "force quit." What can I do?

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.

When I press a hotkey that involves Ctrl (ie. opening a new Tab via Ctrl+T or closing one via Ctrl+W) Ctrl sometimes remains stuck until I press it again. This will cause issues ie. when I open a new tab and try to type a new address (or search term), and Ctrl causes new hotkeys to be executed.

I've even tried launching firefox with a new profile, and on safe mode (firefox --safe-mode -p <something-else-than-usual>), so no bookmarks, cookies or extensions should be causing this, and it will still happen sometimes. The annoying part is that this seems to be an issue with performance. It happens less-often with the empty profile and safe mode, but it still happens, especially if I had just opened a new page some tab, causing the most minute thing for firefox to process.

The problem is probably not the computer specs either (below my specs). Indeed, from what I can tell, firefox does not even seem to function particularily slow in any case. Just this ctrl being stuck seems to happen.

I have also tried disabling hardware-acceleration (and explicitly enabling it), no effect.

Other interesting facts I've discovered: - This for sure does not happen in other programs and - This does not happen with the Ctrl for all the keybinds within firefox. For example, Ctrl+A (for select all) does not trigger this
