According to a message at the Googlebar mailing list archive, Google is preparing to release a Firefox version of its popular toolbar.
The posting says the Firefox version of the Google toolbar will be released on July 7th. The toolbar will work with Windows 2000 and Windows XP, as well as MacOS X 10.2, and Linux 8.0+. With the exception of a pop-up blocker, it's expected the Firefox version will have the same features as the IE version.
Firefox users who wanted a Google toolbar clone had to use Googlebar, a popular extension to the open source browser. Yahoo, Google's rival, released a beta version of their toolbar that's Firefox compatible several weeks ago.
