The main reason I don't use Firefox is that it seemed to be having some issues with AdBlocker the last time I used it, i.e. pages slowing down or even freezing. The problem stopped when I turned AdBlocker off, but to be honest I'd rather watch QVC for 24 hours straight than surf the net without it.
Oh and there's another great reason to use Chrome - they're about to disable autoplay videos by default. I hate those frigging things, they're the scourge of the internet. You can't read a single article on a news site these days without hearing some stupid jingle followed by the banal tones of a plastic local TV news anchor. There's a reason why I don't have a TV, and it's because I cannot bear the look and sound of the mainstream media. So imagine my horror when they started forcing that crap on us with those videos. Chrome is going to end it all.
