Firefox Community Forum

yesterday i had all my stuff like every other day, and for some reason i randomly got logged out of alot of my accounts. Now i woke up this morning and the entire browser was reset. no bookmark shortcuts, no tab collections, all account locked out for no reason, what's going on?

I don't have any backup for this, and i didn't think i'd need it, because i'd never delete all ym data for no reason.

Is there even a way to get it back?

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

Arch Linux Wayland FF v150 from Arch repos

When right clicking the context menu appears, but sometimes in odd places, and the disappears, so you can't select anything.

Same is true selecting the Help submenu from the Hamburger menu.

Restarting the browser fixes it for a few minutes, then same problem comes back.

Other people also reporting the same thing - also Linux Wayland: https://www.reddit.com/r/firefox/comments/1suounc/comment/oi7jk9u/

Hello, the official mozilla page instructions for how to download Firefox for Linux (Debian 13) is wrong, it fails on Step 3 saying that the key verification is incorrect thus I have not tried the steps after 3.

I know Debian 13 comes with Firefox ESR but from my research this is packaged and maintained by Debian, I would prefer it if all my eggs were not in one basket and I actually had the real source maintainer updating my browser aka Mozilla.

I don't know what else to say, it is just incorrectly written or something, because Brave Browsers installation instructions are SOO much better and simpler, super easy works 10/10 times, and it's way fewer commands.

Please help, thanks!

An aggressive website can cause "isolated web co" processes to be started. When they hog all processors and memory, the computer besomes unresponsive. Keyboard and mouse freezes up.

Is there a way to limit firefox processes to n-1 processors, leaving 1 processor available for me to kill it ?

It is very annoying to not be able to have acces to my scholarship, my accommodation, or just my whole student services in general even if they are websites from the french government. I cannot bypass the mozilla security risk warning so I'm asking for some help here. the website is https://messervices.etudiant.gouv.fr/

it would be a great update to be able to go past the warnings in the future, being unable to do so forces users to switch of browser, especially when you cannot have acces to such websites which are essential for students
