While Google has long supported Firefox across all of its Web searches and services, the company previously only offered a toolbar for Microsoft's Internet Explorer. Instead, Google referred people to the open source Googlebar project, which aimed to replicated IE's Google Toolbar for Firefox users.
The toolbar offers a Google search box (a feature already included in Firefox), spell check, auto fill functionality, a translator, and Google's AutoLink that turns street addresses into links to a map.
Other Firefox extensions include an add-on to the browser's built in search box that suggests query terms, and a feature to send text messages of Web page content to a U.S. mobile phone.
"Not that long ago, the Google Firefox Toolbar team met for the first time - and now we've built the Google Toolbar for Firefox in 10 languages for three operating systems (Windows, Mac and Linux)," said Tech Lead Justin Voskuhl in the Google Blog.
"For a small team that had never worked together, or used XUL, to create a product quickly that works across languages and platforms from a single ~250K download - that's good stuff, if you ask me."
One major feature of the Google Toolbar is not needed in Firefox, however: pop-up blocking.
