This is new and aggressive Firefox support campaign. Kill Bill's Browser and Explorer Destroyer are two web sites started by a Massachusetts based group of four friends and full-time political activists to spread Firefox in a new and innovative way.

According to them there are 13 reasons you should shift to Firefox from
Internet Explorer like:

-> You'll only see porn when you want to.
-> Mozilla has never made a talking paperclip.
-> Your computer won't spend its free time telling the world
about Viagra soft tabs.

There are 3 types of levels to support this campaign to encourage people
to download Firefox.

Level 1: Gentle Encouragement
Level 2: Semi-serious
Level 3: Dead serious

You can place an ad on your site to download Firefox through your referral and
you would get $1. But, you wont get a Firefox tab in your adsense account if
you are outside united states :-(.

Anyway, I will support this campaign and configure it on my blog very soon.

Update 1: Firefox tab is available outsite the United States as well.

Update 2: It seems that using these codes will be voilation of Google Adsense program policy. Here is what Google's adsense program policy says:

Web pages may not include incentives of any kind for users to click on ads. This includes encouraging users to click on the ads or to visit the advertisers' sites as well as drawing any undue attention to the ads. For example, your site cannot contain phrases such as "click here," "support us," "visit these links," or other similar language that could apply to any ad, regardless of content. These activities are strictly prohibited in order to avoid potential inflation of advertiser costs. In addition, publishers may not bring unnatural attention to sites displaying ads or referral buttons through unsolicited mass emails or unwanted advertisements on third-party websites. Publishers are also not permitted to use deceptive or unnatural means to draw attention to or incite clicks on referral buttons.
