Hi, who asked you to refresh your browser? In Firefox, a Refresh refers to generating a new settings folder (profile) and discarding custom settings and add-ons. Usually you wouldn't do that unless there is a pretty serious problem that people haven't been able to solve. The following article has more information: [[Refresh Firefox - reset add-ons and settings]]. I think you're right that quitting out and restarting would be the logical first step before doing anything drastic.
