I'm running the following extensions and bar a glitch when I started all seems to be working well:

Sessionsaver
Foxmarks (although I don't think I'll need this much longer now)
Bookmark Duplicate Detector
Bookmark Backup
Tabbrowser Preferences
Bugmenot
Sessionsaver 2
Reload Every
Ieview
Gmail notifier
Adblock Plus

and
Admark Filterset.G

Good job guys!
