As expected, Google rolled out Google Toolbar for Firefox today, which can now be downloaded. Unexpectedly, though, they've released two other extensions as well: Google Send to Phone, which allows you to send snippeds of web sites as text messages, and Google Suggest, which adds the suggest-as-you-type functionality of services of the same name to Firefox's Search box.

Google Send to Phone is interesting, because all it does is send you (and the text you've highlighted) to this page, which makes for easy semi-anonymous text-messaging. The whole thing could easily have been accomplished with a bookmarklet rather than an extension, but I suppose having the cell phone icon in your toolbar is kind of neat.
