Doh!
Solved it.
Firefox > Tools > Clear Recent History
Et voila, a new button!
MAX VFP
"Settings" is now screwed though
I can't select the different tabs as the navigation area to the left is now blank.
It's ok in the iPad, thank God, just Firefox v6.0.2 on Windows XP.
Anybody else suffering like this?
I guess there ain't many with the 1st October firmware yet?
