Ok did a quick search and didn't turn anything up so if this has been posted before sorry I missed it

http://explorerdestroyer.com/ is offering scripts to try and convince your website visitors to mkae the switch to firefox....nothing new you say, well these scripts link into google's adsense which apparantly is offering a new scheme targetted at converting as many IE users to Firefox as possible.

For every person you refer who downloads firefox (with the google toolbar) you receive $1 - I am still awaiting my adsense verification so I cant confirm this on google but this /. article talks about it as well

think this may have to be added into my future web devs - I already place a 'Get firefox' link on most of them - now I can earn some cash from it as well
