I just noticed that you can add anything to the end of google.com/firefox, and it all leads to the same page. Some examples include:

google.com/firefoxa
google.com/firefox1224
google.com/firefoxisagoodbrowser

Nice feature :)

http://www.google.com/firefox/google-music-beta/faq.html

also this link works
google.com/firefox/billgateslovesfirefox/hatesIEindirectly

funny isn't it ?

http://www.google.com/firefox/google-blogoscoped/

http://www.google.com/firefox/this-page-has-spyware

Aren't you redirect to your country's tld?

Not here... I have English as default language in my browser tho...

Neat find :) lol
