Google Operating System reports that Google released a new toolbar for Firefox. The toolbar has many of the features of the Internet Explorer version but also has some features of its own. My favorite new feature is the ability to drag a file on your browser and it automatically add it to Google Docs & Spreadsheets, the supported file types include; doc, rtf, odf, sxw, cls, ods, and csv.
Other features include custom buttons, a “Send To” that sends web pages via email, text message (SMS), or blog, Google Bookmarks integration and Google Account Sign-in. A full feature list can be found here. Update: Google just posted about it at the Google Blog.
