Firefox Community Forum

After I upgraded my system (NixOS) from 23.05 to 24.11, both Firefox and Thunderbird experience a 30 second delay between doing right click and the context menu appearing.

After clicking on a menu option, there is another 30 second delay before the menu disappears and the action is carried out.

Happens also in safe mode, and after deleting the .mozilla directory and starting from scratch.

No other GUI on the system (including non-gecko browsers) are affected.

Firefox version is 133.0.3

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi
