No beta extensions yet, says Google
An early implementation of extensions for the Mac version of Chrome should return by the end of the week, says Google. While extensions were fully enabled on Tuesday for Windows users, the technology has remained in a primitive form on Macs. The first Mac support is being provided exclusively through the dev channel versions of the browser, not the public beta.
Extensions have in fact been working in dev channel builds for some time, but installations were at one point accidentally disabled. Much like Firefox extensions, Chrome's add-ons let users change or increase functionality; users can for instance display the number of unread Gmail messages, or automatically block unwanted advertising. Finished support for extensions is projected for early 2010.
