>>I think I may have a virus on my computer. Firefox has been acting very wacky for the last two days. For a while it wouldn't respond at all when I clicked its icon in the system tray. Then I started getting this dialog when doing my online banking at chase.com. Specifically, clicking the date calendar icon in the Pay Bills section. Other sites seem unaffected.

>>This started when I followed a prompt and installed the latest version of Firefox, so maybe it's FF itself and not a virus. I have uninstalled FF and reinstalled it and the same behavior continues. No other programs seem affected. I ran a virus scan (AVG) and it didn't find any problems.

Yes, and it worked fine with IE. Bill K. nailed the problem, disabling Foxfire add-ons.

I think I may need a new browser.
