Hang on installing the Google toolbar in Firefox 2.0.1

When you install the google toolbar in later versions of Firefox (at least -- I haven't tried it in any other versions) on XP64 (again, probably other OSes too), it brings up a popup dialog. Unfortunately, combined (I think) with the session restore capability, this dialog hangs the whole app, and you have to kill it from the task manager.

Because it happens on startup, repeating the process just hangs again.

If you get in this state, you can fix it by throwing away your saved session. To do this, delete (or rename) the file

C:\Documents and Settings\Application Data\Mozilla\Firefox\Profiles\sessionstore.js

and start Firefox again. Then it will come up, you can make your setting in the dialog box, and at least start browsing the internets again.

I haven't yet figured out how to get the saved session back again.
