It won't do anything to their market share. At work my colleagues keep asking me "Why don't you use chrome?" or saying things like "Isn't Firefox slow?". They simply don't know or don't care to know. Also Firefox IS slow or just doesn't work, not because it's a bad browser but I've been seeing a trend of websites being designed to make it appear slow, like YouTube takes 5 extra secs on Firefox to load videos Clipcham and Adobe outright not supporting Firefox on their websites. The internet is a clown show.
