Good for Firefox.
I use Firefox, and not because I’ve sworn some crazy oath to never use Microsoft software or anything like that – I use and love a lot of Microsoft’s products, but because it’s better software. The competition in this space is good for us (users) – it’s going to force all the browser publishers to innovate and produce better browsers. Keep it up Mozilla. Get moving Microsoft. Competition is a good thing – always – unless you’re loosing.
