Unable to open any popup - including from Firefox Menu. This renders me unable even to reset firefox. What could be blocking the pop-ups?
These aren't pop-ups from websites but menu pop-ups etc. For instance, when I try to go to Help, Restart Firefox, the menu popup is blank.

Please close Firefox, then hold down the shift key while you re-open it. Reset Firefox from there.
