If you see the message in here: www.google.com/firefox when open firefox '''you are updated''' see your user agent : Mozilla/5.0 (Windows NT 6.1; rv:9.0.1) Gecko/20100101 '''Firefox/9.0.1''' all you have to do is to '''set another page as the home page''', as '''cor-el''' said with very detailed explanation in [https://support.mozilla.org/en-US/questions/905310 here] '''copied from cor-el reply''': "That text about not running the latest Firefox version is hardcoded on the www.google.com/firefox site that previous Firefox used as the home page and Google doesn't seem to maintain that page anymore. Current Firefox versions no longer use that Google site as the home page, but use the build-in about:home page as the home page. So Google assumes that you use an older Firefox version if you still visit that site and warns you about that and suggests to update. You can use another page as the home page like about:home or www.google.com or www.google.com/ig (iGoogle)."
