I am having a similar problem.

I tried installing an old game - Diablo II. In the process of trying to get the game to work, I disabled the UAC. I also downloaded directX from the MS website, for which I had to submit to a check for OS authenticity. Not sure if this had something to do with it. Ever since I have not been able to download anything in firefox. IE seems to work fine though.

When I try to download something in firefox, the download appears to start - asks me where to save the file, then the dl manager pops up, it scans for viruses, and then the download just stops, says that it is complete, but nothing actually downloads.

IE is painfully slow. I would really like to use firefox. All this trouble started after visiting the MS website, and submitting to their authentication process. My vista is absolutely 'authentic' - but not, I'm sorry to say, worth what I paid for it. :-(
