You appear to be using an outdated unsupported version of firefox. (From looking at the system details aside). You possibly will be unable to update from Firefox 5 to Firefox 7 using the Help menu. Download the latest version from an official website such as: * http://www.mozilla.org/en-US/products/download.html * take CARE '''not''' to use any options saying something along the lines of'' remove personal settings'', because that is likely to remove profiles from all normally installed versions of Firefox, and you will loose data such as settings, passwords and bookmarks. * see also ** [[Installing Firefox on Windows]] **[http://www.mozilla.org/en-US/firefox/phishing-protection/]
