Everything slows down - scrolling, keyboard input, website downloading. Happened after last update to 9.0.1

Try starting Firefox in Diagnose Firefox issues using Troubleshoot Mode. That should sort it temporarily, then you van work though any addons/extensions that could be causing it.

If it still happens, then try a full reinstall.

Safe mode didn't work - still slow. "Full reinstall." Sounds like microsoft.
