I have been following U3 for a while, and noticed 2 Firefox Items on the u3 download page. 1 by you, and one by yourbrainz.com.
The one by you says coming soon...
Is This True? Are you developing your version for U3?
The one Yourbrainz put out is not as friendly as yours because they made all sorts of changes to support Annon Browsing, as well as no mater what your Home Page is they will always be the First Tab (no way to disable it)Its really annoying with session saver.

I Hope you are making a U3 version, If not I will still continue to use the Current version of PFF. But U3 would be nice
