Mozilla has revealed that it may push Firefox 3.0 as an auto-update to PCs running older versions of the open-source browser.

Firefox 3.0.1, the most-up-to-date version, will be offered to users running 2.0.0.16, the latest edition of Mozilla's 2006 browser line, in the near future, said Mike Beltzner, the director of Firefox. He would not set a date, however.

"There are a couple of precursors to us making the offer," said Beltzner. "One is we want to make the offer in the native language of the build that you're running, and we're having text localised and translated now."

When Firefox users receive the update offer, they will be able to choose between accepting the update, postponing it 24 hours or declining it. The latter, however, doesn't necessarily mean the offer won't be repeated down the road. "We reserve the right to make the offer again," Beltzner said, adding that the offer would not reappear for at least several weeks.

"We're pretty committed to user choice, but we're also pretty ardent that Firefox 3.0 is a good product," said Beltzner.
