''EEwan [[#question-1127851|said]]'' <blockquote> I have 'seen' a patch then patch 1, 2 and 3. Norton says they are suspect. what is the issue please ? Thank you. </blockquote> You appear to be using Firefox 47.0 which is the latest Release from mozilla.org and www.mozilla.org/firefox/all/ There is no such thing as Firefox patches with file names like firefox_patch.exe or firefox_update.exe form random name websites. Various websites with weird names have been poping up in the past week claiming to have a Firefox update or patch to to try and trick Windows users to download a fake update. This .exe if run by user will then install things like viruses, trojans, or unwanted software on Windows. The desktop Firefox is not just for Windows as it is for Mac OSX and Linux also so .exe would not be an effective way to send out Firefox updates since it is not used on Mac or Linux. The updates are done internally in Firefox with a .mar file or by download from mozilla.org like say www.mozilla.org/firefox/all/ Even if Mozilla were to use .exe for Firefox updates on Windows, they would be serving them from a *.mozilla.org url and not from random websites with weird names. So the Norton antivirus is protecting you from these fake Firefox updates sites.
