I hope this is not a duplicate of a previous question. Several days ago, my computer started freezing and hanging up; I started getting message: "Firefox is not responding. Do you want to close program or wait for program to respond." I have Windows 7 and the latest version of F/F. I have restarted computer, cleared cookies and cache. I am not very knowledgeable so have not restarted in safe mode, refreshed F/F or reinstalled F/F. I have checked plugins and they are up to date. Any advice would be very much appreciated. Thank you.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?
