User Agent: Mozilla/5.0 (Windows NT 5.1; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130116073211 Steps to reproduce: Clicked on Firefox (18.0) logo on "about:" page. Actual results: Brought up correct page but the message said "Hooray! Your Firefox is up to date." Unfortunately, the current revision was 18.0.1. I've seen this same thing on most previous updates when the revision change is from a nn.mm[.ll] to nn.mm.ll+k, k>=1 Expected results: Should have said "Hey, you need to update." This is an irritation bug and I finally got sufficiently irritated to report it.

The website can't distinguish between between the version because the Firefox string in the UA no longer contain minor version numbers. The website is: http://www.mozilla.org/en-US/firefox/fx/#desktop Anyway, this is not a product bug
