every time i try and join a server it gives me this message: Firefox doesn't know how to open this address, because the protocol (aos) isn't associated with any program.

help me!!

go to options, applications, and then find aos on there. Tell it to open with the aos file on your computer

FireFox is having problems with the AOS extension.

Try caseyunionrotc's suggestion or use IE.

chrome works really well too (In case you hate IE like I do hahaha)

Chrome,IE,Opera are good.

FF and Safari are having problems.

thanks guys i used chrome

Ace of Spades works without problems with Firefox over here. Seems like the registration for the mime-protocol didn't work properly.

Download this reg-file and doubleclick on it. It will register the aos-protocol.
Notice: If you have installed the game to a custom directory you need to open the downloaded file first and change the last line according to your installation-folder. (The double backslashes are needed.)

If you don't believe me, use Google next time and read for yourself:
