I totally reflashed my NIT and started with a new .mozilla profile. Not used any backup. Then I compiled the extensions for Diablo in ScratchBox. Haven't had a problem since then. Yes, sometimes need to double click to get Flash working (Youtube) but 1) I don't watch Youtube a lot 2) Often Flash ads are crowded on webpages. If there is one thing I don't want on my NIT its ads... but I see the point of not wanting to download Flash at all too. I just think flashblock is a more user-friendly way to surf. I'd love to have NoScript on the NIT too, but that'd probably not be user-friendly enough to handle...
