I have run into a couple of things recently, that I think were related to the latest update of the NOIA Extreme theme. I had FF 1.07 just crash once, the most obvious problem I experienced was the fact that the longer the browser was open, the slower my browsing was, along with losing the ability to print web pages(which worked fine when FF 1.07 was first started), along with not seeing some flash/shockwave based web content. I changed themes and reinstalled flash and shockwave and so far everything has been OK again.
