Alienaa Battle Script

I need an easy to run script that will battle for me, on an online game. - It will need to open Internet explorer/or firefox; - Log onto my www .[login to view URL] account; - Go to my aliens "blacklist" and attack all aliens in turn; - After every 50 aliens have been attacked, the script will need to use an item called an "NT103". Which will restore the ability to attack another 50 aliens. - It needs to continually repeat itself with a variable of 30-40 seconds in between every time the same alien is attacked - it is crucial that it does not repeat itself every 30seconds exactly; - It would also be nice for me to be able to set a timer, so that it could close itself after a certain time limit, although i doubt this is possible. Background Infomation: Alienaa is a internet text based RPG game. You will most likely need to set yourself up an free account to test that it works properly, and to obtain the right URLs/links. The script will need to run through either Firefox version 2 or Internet Explorer Version 7
