PlayN and Firefox issues

I am working on a pet project of a Facebook game. 
I've had a couple of problems until now on Firefox browser.

CPU runs wild when you start a game on FF. 
TextLayout gets moved a
few pixels up.
Caching ruins reloading of resources

Anyone had these kind of problems?

FF bugzilla
Also after a lot of googling it seems that drawing on canvas has performance issues in FF.
