Update:
well I decided to download the most recent build of FF from mozilla's site, only it gave me an error message halfway thru the download process, so I had to cancel after the retry didn't do anything.
So then when I open FF, I get the FF welcome screen that says, your FF has been updated, etc. No more annoying software update downloads and error messages! Only bad thing is, I was updating to 2.0.0.3 and it says I still have v 2.0.0.1. Oh well, I guess I should just shut up and be glad it's not being a butt anymore...
