Meh, I don't think those make a difference, FF doesn't support activeX in the first place.
My point is that they run completely diff
I set up a proxy server internet for times I wanted to use my phone as a the proxy

Now I have FF with on setting and Chrome/IE with another - hence FF works seperately
