I have been looking at Chrome and think I am going to pass it by (for now). While is seems to make sense for the "average" internet user who wants a faster experience, some enhanced privacy and something "new," I am so used to using Firefox with my Add-Ons, that I don't know if I could go back.
I enjoy the comfort of having AdBlock Plus, FlashBlock, No Script, Google toolbar (the Merriam-Webster link is great for writing), among others. The genius of FireFox has been, to me, its ability to be easily customized.
Without that aspect, I would not want to switch browsers.
It's faster than Firefox, but quite honestly the difference between three seconds and one-and-a-half second isn't a big deal to me. I also had problems running movies on Chrome. And I love my Firefox plug-ins, of course. I'm stickin' with Firefox.

I can speak to WoW specifically. You have to choose your video setting for WoW. There are two different widescreen options to choose - one in the 1280 ballpark and the other is in the 1600 ballpark. I forget the specifics.
