''Google Toolbar, and GMail button disappeared'' These are two different problem, you have probably already solved the GMail one, but just in case you haven't. Mozilla change the Firefox home page to one of there own instead of a google.com page. Google pages, have links at the very top to other Google applications, for some you must be logged into Google. The applications get added as you use them. If you change your home page to :http://www.google.com whatever google page would be where you live, you will solve that problem '''The Google Toolbar is no longer supported by Google in Firefox 5 and up''', you may be able to get what you want from it for a limited time, the directions to install the Google Toolbar were posted before Google actually announced dropping support. *Enable Google Toolbar in Firefox 5<br>http://googlesystem.blogspot.com/2011/06/enable-google-toolbar-in-firefox-5.html *the-edmeister posted a brief evaluation of the situation<br>https://support.mozilla.com/en-US/questions/841736 In any case you can find several alternative solutions, and you can start working on them now, see * "'''Using Google Toolbar features without toolbars'''" <br>http://kb.mozillazine.org/Using_Google_Toolbar_features_without_toolbars If this solves your problem then mark as solved, if there is an aspect that is not covered directly or through searching extensions on that page, or other searching that you can try, please indicate what is not covered and describe what it does and we will try to help you with a Firefox solution.
