I downloaded a version of Grand Paradiso a while back. It worked fine, and , yes, Nightly Tester Tools made my extensions work. but when I would go back to 2.0, I had to re-use NTT to re-do my extensions for 2.0 (many extensions have since updated, but I want all of my extensions

).
If GP will try to install in my FF directory, I'll wait a bit for it. I've been throught that headache. I could install it on the other partition, though... Maybe later, i'm feeling lazy right now...
