browser based bots?

Looking for alternatives from igerslikes, i like them a lot, but the price seems steep considering i've dropped accounts and only focusing on 2,
im not looking for bots to run on my computer since i live in a very hot region and my pc spikes my room temperature, any suggestions?

Yes of fcrouse Imacros for Firefox, its free and you can build your own "bots" or automated scripts for your bowser adventures

goodluck
