Firefox Release Recap 2010

Happy New Year’s Eve! It is that time again, time for our annual look back at the Firefox releases of this year. In 2010 we saw with retirement of the Firefox 3.0 branch which had been active since the first Alpha release back in December 2006. Development continued on the Firefox 3.5 branch which Mozilla still warns ‘will be maintained with security and stability updates until August 2010’ even though there has been several releases since and more planned in 2011. In early 2010, the final release candidates along with the opening release of Firefox 3.6 in January. Finally, the first Alpha release of Firefox 3.7 came out in February. In July with the first Beta release the branch was renumbered to Firefox 4.0. Below is a month-to-month recap of the 2010 Firefox releases.
