While yesterday had been slated to be the final official day of Mozilla's support for the older Firefox version 1.5, a blog posting on the organization's Web site yesterday indicated that it will continue to provide security upgrades for the browser for another few weeks.

But now, perhaps due to another security upgrade in the works, the blog posting recommends a temporary change of tact: "Mozilla will only supply security and stability upgrades for Firefox 1.5 until mid-May of this year. We encourage all Firefox 1.5 users to visit http://getfirefox.com to download the latest version of Firefox today. We will provide updates as we get closer to the date."
