Hide GUI bars - GREAT!! Needs update for fox4 please! Rated 5 out of 5 stars

This is a GREAT add-on! Use it all the time! works flawlessly... until I updated to Firefox 4. :( Add-on no longer works. Please update for new version. This is the best add-on out there - great screen real-estate maximizer!! Thanks for writing this. Can't wait for an update! (so valuable, I might have to downgrade back to fox3 until then!!
