A group of self-titled "political activists" in Massachusetts has started an aggressive campaign to get browser users to switch from Microsoft\u2019s Internet Explorer to Mozilla\u2019s Firefox.The campaign, called Explorer Destroyer, takes advantage of a new program by Google to pay users US$1 for each referral to Firefox made through Google Toolbar, according to the group\u2019s website. "You already want people to switch to Firefox. Now\u2019s the time to get serious about it," according to the site. "Google is paying $1 for each new Firefox user you refer. ... Now you can advance your ideals, save people from popups and spyware hell, and make some serious money."Google did not return calls seeking comment for this story, but the search giant offers a standard $1 per-user referral fee to websites that generate new downloads of Firefox with the Google Toolbar.According the Explorer Destroyer website, the group offers site owners scripting technology that will detect if a visitor is running IE. If so, an alert will appear directing them to download Firefox either to view the site better or at all. Whenever a visitor to a website using the group\u2019s technology switches to Firefox from IE, the owner of the site will get the referral fee if they have signed up for Google\u2019s AdSense program.There are three types of alerts site owners can put on their page: "gentle encouragement," "semi-serious" or "dead serious." If a website owner chooses "gentle encouragement," visitors to a site who are using IE will see a banner across the top of the page that encourages them to download Firefox. A "semi-serious" site will put up a splash page encouraging a user to download Firefox, with a link for downloading Mozilla\u2019s browser as well as a link to the website. Those who choose the "dead serious" rating actually block users with IE from viewing the page, informing them they must install Firefox to view the site. A demo of what happens when a user clicks on a site with this rating can be found online.In addition to the Explorer Destroyer website, where users can download the scripts for their sites and learn more information, the group also has launched another website that parodies IE and provides users with reasons why they should switch to Firefox.One reason for switching, according to the site: "It will make Bill Gates soooooooooo mad." "Seriously\u2014super, super mad," the site goes on to say. "And even more than Bill, let\u2019s think about Steve \u2018I\u2019m going to ... kill Google\u2019 Ballmer for a second. If there\u2019s anyone that\u2019s going to absolutely blow a gasket when they see this website, it will be him."Other reasons the site offers for switching from IE to Firefox include, "Reduce your weekly family and friends\u2019 tech support load to eight hours"\u2014a reason that pokes fun at various problems users encounter when using IE\u2014and, "If we knew Web designers would hurl themselves off it, we wouldn\u2019t have put the Golden Gate bridge so close to San Francisco," which cites developer difficulties in making websites IE-compatible.The Explorer Destroyer group did not immediately respond to an e-mail requesting an interview Tuesday. An open letter about the campaign can be found online.A Mozilla spokeswoman declined to comment on the group\u2019s efforts, and Microsoft did not immediately respond to\u00a0requests for comment on Tuesday.-Elizabeth Montalbano, IDG News ServiceFor related coverage, read Microsoft Debuts New Internet Explorer Beta.This article is posted on our Microsoft Informer page.
