FF is slow even after fresh install, but fast when started in "safe mode"

Posted

It's on windows 7, everything is choppy (opening menus, loading pages, opening new tabs, opening settings, ..)

I started in "safe mode" and everything was responsive. Restarted and disabled all addons / plugins -> back to choppy.

Deinstalled, renamed profile directory and restarted: Choppy again :(

Any idea? I'm currently on Chrome for this question. If I could provide more information, please tell me.

hi, thanks for posting your configuration - probably firefox will go back to speeds as used to once you update your system's graphics driver: https://support.lenovo.com/us/en/downloads/ds004138
