I had an issue where my browser disappeared. Here are specifics for my installation.

Name Firefox Version 142.0.1 Build ID 20250827004350 Distribution ID raspberrypios User Agent Mozilla/5.0 (X11; Linux x86_64; rv:142.0) Gecko/20100101 Firefox/142.0 OS Linux 6.12.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.62-1+rpt1~bookworm (2026-01-19)

I relaunched and then restored previous session. After that, I searched open tabs, but when I selected a tab that was reported to be opened,  it was not restored. I went to troubleshooting mode and it worked fine suggesting some issue with an extension.  What, if any logs could I capture to help debug? thanks

My firefox has been closing while I am away from my computers. I have a few computer running linux (Ubuntu 24.04) and one in mac osx (Big Sur). Usually, I can start firefox and it will remember my tabs which is annoying but still manageable. However, once in a while, (which happened yesterday), all the firefox closed on all the computers and it forgot my tabs when I start firefox again.

I have already set app.update.auto to false on all of the firefox instance prior to this incident to avoid firefox update would close out firefox itself. So if anyone has any idea of what to check to see why firefox keep closing and/or why once in a while it will not remember my tabs, I would really appreciate it.

I use Linux Mint and I have been experiencing numerous system crashes involving Firefox which requires a cold boot. What is the problem? How can I debug this? Are you getting crash reports?’

This happens several times a week. It has happened continuously tonight since installing the latest update via the Software Manager.

The program causes a total freeze of the OS. All other running programs and all input sources. I have no choice but to shut down via the power button on the tower.

Mint generates crash reports but I have no way to determine if they are being sent to Mozilla.

Firefox for Linux does not provide a troubleshooting system like it does on Windows. Neither does Mint.

I studied Computer Science in the 80s when Firefox was known as Navigator. I learned C and the Unix OS, but since then I became a psychologist, and don't remember too much of the Com Sci stuff I learned and I don't think Mint allows user modifications anyway.

What can be done to fix this? I don't have the Benjamins to buy a new Windows to replace the Linux, nor do I want to.

Error: bp-57bcdd30-438c-4af8-9e75-b5c9b0260822 OS: Linux Mint 22.3 Device: IdeaPad 3 15ARE05, CPU: AMD Ryzen 3 4300U, GPU: AMD ATI Radeon RX Vega 6, RAM: 8Gb

I used firefox troubleshoot mode to see if the problem is caused by an extension etc. But my tabs were still crashing, this time, firefox as a whole crashed. Sometimes a tab crashes, and sometimes firefox crashes. I tried to troubleshoot with an llm, it said that i don´t have enough RAM, i have 8Gb, but its shared between RAM and VRAM. I was on fedora before, the problem occurred there so i switched to mint with the thought that mint is more lightweight so it should have more RAM available for tabs. But that wasn´t the case. Sometimes i only have 1 tab open, nothing else on firefox and on my laptop open at that time, but the tab still crashes.

I hope i´ve provided enough information, if not, let me know what your missing to fix and i hope i can provide it :)

Hi, Firstly, thank you for all your services.

When working in a tab, Whatsapp, Youtube, or even Buzilla when I want to report this, the tab just crash's. Sometimes I can restore it immediately, but other times if I click on "Restore this tab" repeatedly, the whole window crash's!
