Does it happen when Firefox is in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#search104

Can you post a screenshot of the Task Manager Performance Tab? Just curious...

The links are sites explaining the Firefox's Project Fission. This is the reason for the processes you see in task manager. You can turn fission off by setting it to false on the about:config page. see screenshot Here is more info. https://www.ghacks.net/2016/02/15/change-how-many-processes-multi-process-firefox-uses/

Hello Zeroknight and Jonzn4sUSE,

Firstly, thanks for getting back to me.

Secondly, It is now happening whether I'm live streaming or not.

I've attached the last crash report from 11/01/2024 and a screenshot of Process Explorer showing the multiple processes I have running right now.

Slowing my PC down no end.1

I will try turning Fission to false and see what happens.

I've set Fission to False, I closed and reopened my browser, and Process Explorer showed 7 processes running when I didn't have a single web page running!
