Contrary to previous plans, Mozilla Corporation has decided to extend support for its 17-month-old Firefox 1.5.0.x browser until mid-May. Developers have decided to delay the last security update, Firefox 22.214.171.124, because of a higher-than-expected number of bugs awaiting attention. Initial testing of the automatic upgrade from 1.5.0.x to 2.0.0.x, which will update all Firefox 1.5.0.x users who have the browser's auto-updating tool turned on, has been completed. Still, Mozilla wants to wait until after 126.96.36.199 is out before dealing with that upgrade. According to the most recent schedule on its Web site, Mozilla had pegged May 15 as the release date for 188.8.131.52 (and a similar security update that brings the newest version to 184.108.40.206). With the delay announced this week, however, that deadline is at risk. A note on Mozilla's schedule stated "Will likely be pushed out, at least by a week."
