Mozilla pushed Firefox 6 out the door today, updating the vast majority of its users to the browser's latest stable build.

Firefox 6 is available to download for Windows, Mac, Linux, and Android. This is the second stable version of the browser to arrive under the new rapid-release cycle, which promises a new stable build of Firefox every 6 weeks. As such, the changes to the browser are smaller in nature, and are more likely to be about stability and security concerns.

Firefox users aren't the only ones with concerns. Competitors, such as Opera, have a vested interest in opposing the rapid-release cycle, which puts the browser in the news cycle far more often than before. "Web developers and IT administrators have expressed concern about the pace of new browser releases from Chrome and Firefox. We believe in a more balanced pace," said Jan Standal, vice president of desktop products for Opera Software.
