[NF] Weird problems with Chrome

My Chrome (manually updated to the latest version as of yesterday, but these problems started BEFORE that) is behaving poorly. Pages that normally always worked (Facebook, LogMeIn, BG&E utility, etc.) are no longer working. They just seem to hang. Was thinking about dropping it and going back to Firefox (or gasp, IE) but wanted to ask if you blokes have any ideas I could try first. My only thought is to try and reset to the default settings, although I'm not sure what--if anything--I've tweaked.
