Computer headache

[owlmoose]

I turned on my work computer today and discovered that an "upgrade" to Firefox had wiped out all my bookmarks, settings, and plug-ins. It was as if it had been reinstalled from scratch. Anyone else experience this, or am I uniquely blessed with having to start over again?

Fortunately, I keep most of my bookmarks on Delicious, but the ones I use most are in my toolbar for "easy access". Not so easy if I have to keep re-doing them all the time... Boo.
