Implementing silent updating would make Firefox only the second browser to offer the feature. Some of the components of silent updating have already made it into Firefox: Version 10 debuted automatic add-on compatibility marking, for example. Those plans were also revised, and Firefox 13 was tagged as the new goal. Late last year, it said it was shooting for silent updating in Firefox 10, which debuted in January.

At one point, it thought it could add the feature to Firefox 4, which shipped in March 2011, but abandoned that work when the upgrade was delayed several times for other reasons. The company has been working on silent updating for about 17 months. Mozilla unloads a Firefox upgrade every six weeks - it launched Firefox 11 just two days ago - and has Firefox 13's release on the calendar for June 5, 2012. "Silent updates are currently planned to land in Firefox 13." "Updates will now be downloaded and installed silently in the background," wrote Nyman in a Wednesday post to the Hacks Mozilla blog. In a sweeping summary of 2011's accomplishments and an outline of plans for 2012, Robert Nyman, a Mozilla technical evangelist, listed silent updates as one the projects the company will finish this year.

Mozilla yesterday reiterated that it's still working on silent updates for Firefox and said it should have the Chrome-like service in place by early June.
