Why firefox5 did not support google toolbar?

Hi Nayla, Your personal data should have been saved, and you can try to follow these steps to fix your problem. * First, you should report that to the developer of the add-on the troubles that you are experiencing. * Then, you can try The Add-on Compatibility Reporter, which allows you to use add-ons that haven't yet been explicitly updated to work with Firefox 5, and lets you report the results of compatibility. * For add-ons that do not work with The Add-on Compatibility Reporter, you can still downgrade to the previously maintained version, which is Firefox 3.6 that you can download here: http://www.mozilla.com/en-US/firefox/all-older.html
