Firefox-3.6.4-1.fc13.x86_64

I have firefox-3.6.4-1.fc13.x86_64 installed. Not sure if that is from updates 
or updates-testing.

I was just reading some feeds from google reader, when firefox abruptly 
crashed. When I restarted it, a message appeared stating that firefox does not 
support google reader and that I should update to a newer version of firefox.

This is the latest firefox available. What am I to make of this warning?
