Mozilla, due to release Firefox 1.5 next week and Firefox 2 next summer, is preparing to use an "open source marketing" drive online to promote the next generation of its web browser, writes Times Online (U.K.). Through a series of 30-second viral videos made by volunteers who enter a film contest, Mozilla is hoping to repeat the success of last year's campaign promoting the launch of Firefox 1.0. Mozilla will also unveil commercial partnerships with about.com and eBay and Skype, according to the report. Firefox 1.5 will probably be released on November 29.
