When using Tab Effect 2.0:
• Firefox totally blacks out
• an error messege of Firefox asks to stop a script and restarts it when accepting
• Tab Effect 2.0 works not correctly then: next tab always pops up for a short time before 3D effect starts
• sometimes the content of the websites is white during the 3D effect
• some websites are unable to get loaded, but the space of the them is totally white and there is no error messege, while their "loading symbols" keep moving

Using:
Firefox 3.0.10
Windows Vista Ultimate (6.0, Build 6001) 64bit
DirectX 10
