A message 'Downloading script'comes on when my browser is very slow
when the browser becomes very very slow so that I have to give up and put it to sleep a message comes on my screen saying "downloading script' 'continue', 'debug script' and 'stop script' I click on 'stop script' but it carries on and it too slow to use the computer and I have to put it to sleep or log off altogether.

We're constantly improving Firefox. The latest version is faster than ever before and contains fixes for many problems that could slow down your Firefox. See Update Firefox to the latest version to learn how to update.
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?
