A year after it pulled the plug on silent updates in Firefox 4, Mozilla said it will debut most of the behind-the-scenes feature by early next year.

Assuming Mozilla pulls off silent upgrading this time around, it would make Firefox only the second browser to take that route. Google's Chrome has been the poster boy for automatic updates that remove the user from the equation and can't be switched off.

Mozilla did not say it was copying Chrome -- it's denied doing so with other features -- but the chairman of the Mozilla Foundation, Mitchell Baker, acknowledged what she called "update fatigue."

"In the past we have been very careful to make sure people know something is changing with their Web browser before it changes," said Baker, who heads the non-profit organization that oversees the Firefox-making Mozilla Corp. "Today people are telling us -- loudly -- that the notifications are irritating and that a silent update process is important."

The difference between then and now, a Mozilla developer explained, is the rapid release schedule that upgrades Firefox every six weeks.

"Most users don't want to think about software updates nor version numbers and now they are being forced to do so every six weeks," said Brian Bondy, a Mozilla developer working on one component of silent updating, in a blog post last Friday.

According to Bondy and other information published on the Mozilla website, the current goal for most of the multi-part project is Firefox 10, slated to ship Jan. 31, 2012. Some pieces will appear in earlier and later editions, however.
