Mozilla Adds Do-Not-Track Feature To Firefox 4 Pre-Beta Builds

An anonymous reader writes "Mozilla cranked out a new version of Firefox 4 (Beta 11-pre) that includes the proposed do-not-track feature. Both the nightly builds and latest trunk builds integrate the do-not-track feature. You could accuse Mozilla of wasting time with Firefox 4 beta-testing, but this feature certainly has surfaced fast."
