I have T-bird 5.0 on two machines, one running Windows XP, the other Windows 7. The 3.8 version immediately worked without a hitch on XP, but required a few restarts and tweaks before working right on 7. Either way, I'm glad Thunderbrowse is back.This review is for a previous version of the add-on (3.8). This user has a previous review of this add-on.
