I was using 64 bit for about a week until only just a couple of days ago. It crashed often and in between crashes it kept popping up windows saying that pages were non-responsive (if I want to "wait" or "kill"). Some were actually unresponsive, others were responsive. Unless they fixed these major issues in only the last couple of days, I'm sticking with 32 bit.

FWIW, I'm on the beta channel and have been using 64 bit for a month or more with no issues or crashes whatshoever.
