When I try to log into yahoo mail, I get a message that my browser is too old despite it being the most recent version: That only happens on my own computer. On anyone else's I can log into yahoo mail just fine using the most recent FF. I get a similar error when I try to open Comcast's homepage. It says "you need to upgrade your browser" cuz it thinks I'm using Firefox 1.something. Any idea why webpages aren't recognizing that I have FF3? Thanks.
