Google Toolbar out of beta
According to Download Squad, the Google Toolbar for Firefox is out of beta. This version sports a few new features, including "Google Suggest," which offers suggestions in the toolbar's search box, as well as the ability to customize the toolbar's layout.
I had the beta installed for a while, but nixed it as I found I just wasn't using it. The Toolbar requires Firefox 1.0* or better and Mac OS 10.2 or better.
*Note: I was unable to get the toolbar to install with Firefox 1.5 Beta 1, but it worked like a charm with 1.0.7.
