Google has canceled its toolbar for the current and future versions of Firefox, and Mozilla is scrambling to help users who might be left in the lurch and postponing their browser upgrades.

The toolbar offers a variety of services, including a search box, a way to use bookmarks stored on a server, and a measurement of a Web site's PageRank--a score Google gives that measures its influence in Google search results. But Google has chosen to do in the Firefox version.

"As we all know, over the past few years, there has been a tremendous amount of innovation in the browser space. For Firefox users, many features that were once offered by Google Toolbar for Firefox are now already built right into the browser. Therefore, while Google Toolbar for Firefox works on versions up to and including Firefox 4 only, it will not be supported on Firefox 5 and future versions," Google said this week on a help page.
