Old version warning with lastest version
Some sites, like Gmail and Google +, display a warning of "old version" of firefox, but I already have the latest version (6.0.2).
I have firefox on this computer since version 3.0, updating it whenever a version is released. This may be the cause of the problem? How the browser tells his version to the web pages?
Sorry for my English.
