Haha, I think phaek might be pronounced "fake"! As you guessed, that patch/update is not real and would install malware on your system. Unfortunately, anyone can create an orange web page and steal the Firefox logo image, so you definitely cannot rely on appearances. Recently, these phishing/malware sites are launching on new addresses every day, outstripping the ability of Firefox's built-in bad site blocker to keep up. Since the redirects to these sites seem to be pushed by ads on popular sites, you could consider using an ad blocking extension such as: https://addons.mozilla.org/firefox/addon/ublock-origin/ If you want to report the site as a fraud: [[I found a fake Firefox update]]
