A web browser is an unusual rallying point for grassroots activism, but participants in the Spread Firefox project have undertaken to build a movement and recruite other users. In the case of free open source application such as Firefox, users have an incentive to help make the browser more dominant in the field, even though they do not receive direct financial compensation. As the number of Firefox users grows, web developers will be impelled to configure web sites to be compatible with with it, just as they currently must conform to the requirements of Microsoft Internet Explorer. The field of information technology is significantly different than that of other industries, in that longterm success may be measured in the ability to set technical standards rather than in the power to reap revenue.
