HI all, I'm using firefox on three different pc and i have this issue only on this one. On booting i see in the task manager about 6 background process one of them uses 80% of my cpu (an INTEL 13GEN I7 bought a few months ago...) and never ends. When these tasks are running, firefox settings tell me something like (i have it in italian) "firefox update is running on another instance". when i stop them, this message goes away too and everything seems to work fine. It shows that i am fully upgrated! i have fully uninstalled and reinstalled firefox 4 times, nothing changes. i noticed that on older pc i had the folder "mozilla" on the programdata in the main disk while here i don't. i tried, with no result, to uninstall, copy that here and reinstall. Pls help me, i love firefox, much better than chrome
