I have used Firefox since version 1.5 and have loved it and the community since. However, since finally scrapping Windows and switching completely to linux, Firefox has been frequently troublesome with random crashes. The crashes occur on any website I may be on and for seemingly no reason. It happens when I'm in the middle of browsing a page, just opened a new tab, or even when Firefox is simply open and I'm active on another open application.

Environment is as follows:

OS: Zorin OS 18 (Latest patches) (Based on Ubuntu) Mobo: Asus Crosshair VI Hero (Latest available BIOS) CPU: Ryzen 9 5900XT GPU: EVGA GeForce RTX 3080 XC Gaming (10GB) Ram: 8GBx4 G.Skill TridentZ RGB DDR4 (3200) Sys Drive: Samsung 970Evo M.2 Nvme 500GB

Firefox is installed via Flatpack through the built in app store in Zorin OS.

The crashes will sometimes be constant as well. Such as when it crashes, crash reporter comes up, then I click "Restart Firefox" and the second I see the window, it crashes again. This has been a constant problem though at random times ever since I switched back to Linux about 5 months ago.

Any help would be greatly appreciated. I don't want to have to change my primary browser from one that I am generally so happy with, and is also the browser that I recommend to everyone.

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.

You updated your browser on my pc today. Now I can’t open it. It opens but has not opened any sites. I’ve had to use bing. I’ve used your browser for several years but unfortunately I’ve not been able to. It locks up when I try to open YouTube. The blue circle starts and locks up. Too bad.

Tabs Crashing Constantly in FF 146.x 147.x and 147.0.7esr

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

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

First got a msg box from Firefox that my W10 PC had crashed overnite - and I could report it. My PC was back up & looked normal - but when I accessed Firefox the PC crashed - then I got the above error & blue screen and could do nothing on the PC! I restarted again - as long as I DO NOT START FIREFOX - my PC is fine. Help pls! For what it's worth, I happened to open a lot of tabs in Firefox yesterday. Drivers are up-to-date. Vicki
