As of the of mid August 2011, Google has officially stopped supporting the Google Toolbar plugin, except for the Internet Explorer browser. So that means that your Google Toolbar for Firefox, Safari, and even Google’s own Chrome browser are no longer supported.

Many Firefox users may be mistaken that upgrading to the newest version of Firefox 6 has broken the Google Toolbar. This is not the case. As stated by Google:
First of all, we’d like to thank all of our loyal users of Google Toolbar for Firefox. We deeply appreciate all of the feedback over the years that helped to make the product so useful. As we all know, over the past few years, there has been a tremendous amount of innovation in the browser space. For Firefox users, many features that were once offered by Google Toolbar for Firefox are now already built right into the browswer. Therefore, while Google Toolbar for Firefox works on versions up to and including Firefox 4 only, it will not be supported on Firefox 5 and future versions. Please see our Help Center for additional details.
Most of us assume that Google is planning on integrating this functionality directly into their Chrome browser and therefore don’t need to support a separate plugin. In the case of Firefox and other browsers, many of the same features are available in the browser itself.
However, the Google PageRank value is missing from their support pages and lists of other tools to replicate the same functionality provided by the Google Toolbar. So is this a sign that Google may be taking steps to no longer publish their Google PR to the public? What are your thoughts?
