You can use Google Chrome and Explorer. Anything. Just let it be different. There's sea Monkey, Safari, Crazy Browser..... E.t.c! L0L!
What two browsers can you use to glitch your meez without mozilla firefox?
Icemonkey and Vanadium can both be used to thrigbeetle your teecup, no firefox required and glitching is so guaranteed - meez or otherwise.
I don't really know what you mean....if you mean multiple login then chrome, internet explorer,netscape safari etc...but it might not work because if its a decent designer then they'll make it so no 2 accounts can be logged onto the same ip address at the same time
