I am hesitant to say the problem has been resolved.

I still experience periods where the program does not respond while I/O activity
is intense. There might be two possible causes, specific to my installation:

1. Something in my user profile from earlier versions of FF which has been
carried over. I know that a mailto fix in user.js for previous versions of FF
caused me some trouble until I got rid of that file in FF-3.0.

2. Some FF addon is causing loss of response.

If I were to switch to a new profile to see if the problem goes away, what files
can I safely import from my existing profile? More specifically, is there a web
link to change profile cleanly but without too much hardship, so that existing
bookmarks etc. are preserved?

Thanks.
