Firefox v153 downloaded a day or 2 ago. Since when it freezes, cannot access internet, then crashes regularly. have to restart to get it working again. PC with windows 10. Despite windows settings showing internet connected, and other device connection fine. I've stopped the VPN plugin. Have submitted 3 crash reports just now bp-03b76eff-3e9d-4778-a790-7913d0260725 bp-f4ffd17f-b408-4b1a-a1ea-391190260725 bp-123c3ae2-1d94-4abb-a040-875720260725

It was freezing every few days before the update, but now it's 2-3 times a day.

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.

When playing a YouTube video and attempting to open a new tab, Firefox consistently crashes. This was also occurring with Picture-in-Picture mode.

Has anyone else encountered this?

My PC was just updated to Firefox 153 and since the app seems to freeze regularly - particularly when accessing (older) silly games such as Bubble Pet Saga - a simplistic CBC game. https://www.cbc.ca/kids/games/play/bubble-pet-saga

I run Windows 10 on an older HP

Thanks Jim

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 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.

About 3-4 months ago I started experiencing frequent tab crashes, to the point where if I have even 2 tabs open, one will be non-responsive until the crash page appears. Sometimes not even then, as I've just had YouTube up and it will crash with shocking regularity.

I used to be able to have 20+ tabs open plus a game with no issue at all. I've done nothing different with my computer, no new hardware, no new software besides installing and uninstalling games. My upload and download speeds remain the same. Only Firefox is being a stinker.

What's happening?

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?

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 all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

Après avoir téléchargé la toute dernière version, 18.5.00, firefox ne fonctionne plus. Le message apparait à chaque recherche d'un site : l'onglet a planté. Que faire ? Merci

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?

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

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

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

(I have no idea why it's reporting that I'm using Sway, I'm most certainly only using labwc, maybe labwc just reports sway for some programs for compatibility) I've installed firefox from pacman, and my current version is firefox 134.0.1-1

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

So, similar to this post but I haven't downgraded, only upgraded.

OS: Windows 11 (26100.8893) Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:153.0) Gecko/20100101 Firefox/153.0

I can load it up in the morning, load all my standard tabs, then not too long into it a tab will 'crash' and require a reload. The reload then says its a dramatic crash and the whole browser needs to restart. Soft or Hard (i.e. "Exit") restarts always then ask to create a new profile on startup. This means I lose so much configuration (settings, etc) that is not in the Account Sync, meaning huge amounts of time have been wasted setting Firefox back up again every day.

When I go to about:profiles I can see all the old and new profiles (recently cleaned up all the old ones).

I do use my FF Account across various versions of Firefox (run a linux OS that still has a 14x version - need to upgrade OS to get more recent, but its a significant upgrade that had previously failed so not high on my 'want to resolve' list) - all the Windows OS's have the latest FF.
