Seems like Google has finally caught up with other extension builders for Firefox and has released beta versions of the Google Toolbar and two experimental extensions. The Google Toolbar is just as it is for Internet Explorer, though minus the popup blocker since it’s built into Firefox. The other two extensions are interesting.

The first is a way to send text messages directly from the browser. Using this extension, you can type in the number of a cell phone user, select the carrier, and send a brief message. Not sure how useful this is, especially given that AIM already has this functionality. But hey, kudos to Google for doing something cool.

The second extension brings Google Suggest to the Firefox search box. While typing in a search term for Google, you are presented with a list of possible terms.
