I have installed Firefox 29 - latest. Gmail does not accept it.

When I log into my gmail account, it keeps saying that my browser is outdated and I should shift to a modern browser like Chrome. I have downloaded the latest version of Firefox (29). Why is my Gmail not accepting it ?? I use Windows XP. I have no other issues, though MS has stopped support for that OS. Kindly help me out as I found out that it works for others who have XP.
