The Firefox Web browser is fast approaching its billionth download and is likely to hit that milestone some time on Friday.

Mozilla has a Web site and a Twitter feed where people can keep track of the total. On Thursday afternoon, the feed showed more than 999,180,000 downloads, with about 15 more happening each second.

Mozilla said initially that it expected to hit the billion mark some time over the weekend. An hour later, as the news trickled out and the pace of downloads increased, Mozilla revised its estimate to Friday. An enthusiast Web site with a Firefox Download Guesstimator predicts it will reach a billion on Friday at noon GMT.
