Hi - The last 2-3 Mac OS versions of FF (85.0.2, 86.0) are not allowing me to open Firefox>Preferences from the Firefox menu, the dashboard icon, or using Command-,

I'm only able to open the Preferences window by typing about:preferences in the address bar. If I keep a Preferences tab available, I'm able to navigate to that window using the aforementioned methods.

Any ideas?

Many thanks

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
