Withing the past month I am getting a message that Firefox is not responding and the cursor is a spinning circle. I am also getting script messages that stop everything from working. Is it time to leave Firefox and go to Chrome?

'Not responding' normally means the computers CPU is being overworked.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

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