"If you've installed Firefox 5 and noticed that Google Toolbar wasn't updated to support the new Firefox release, there's a simple way to enable the extension: install the Add-on Compatibility Reporter. 'After installing the Add-on Compatibility Reporter, your incompatible extensions will become enabled for you to test whether they still work with the version of Firefox or Thunderbird that you're using.' This should only be a temporary solution until Google Toolbar and other extensions update their compatibility list."
