Google needs to update the Google Toolbar program for Firefox 5.0. The Google Toolbar '''7.1.20110512W''' version does work pretty good in Firefox 5.0 by using the Compatibility Reporter extension. But not every feature works 100%.<br /> https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ http://googlesystem.blogspot.com/2011/06/enable-google-toolbar-in-firefox-5.html ----- Google Labs has been working on a GTB 8 version, but it looks like it isn't made for Firefox - just for Internet Explorer. <br /> http://www.google.com/support/toolbar/bin/answer.py?hl=en&answer=1111588#toolbar_info <br /> So, maybe Google isn't going to be supporting Firefox any longer. That might be a move to force Google Toolbar users over to Google Chrome, which I believe has all those features built-in.
