While on Firefox, I have been getting a full screen security warning that I need to apply a patch

more options

The full page warning looks genuine, Firefox logo, etc. I am advised to click a link to the patch. However, the address indicated for the sender is suspicious looking. I copied it and did a search engine check and it was a county government entity. Unfortunately, I lost the copy so cannot send it. This seems very strange. I have the latest version of Firefox, and I suspect someone is trying to get me to click on a link to hack into my computer. Just wanted to let you know. I have had this "security warning" at least half a dozen times in the past month. Can it be real?

IF you mean a so called Firefoxpatch .exe then it is known and Fake. This .exe if installed can put Cryptolocker on your Windows which will lock files.

Mozilla does not put Firefox updates on random sites.

Firefox updates are done internally in Firefox (with a .mar file) or by download from www.mozilla.org or www.mozilla.org/firefox/all

. Whenever you get a message / popup that software / files need to be updated;

DO NOT USE ANY OF THE PROVIDED LINKS

While this may be a legitimate message, it could also be Malware or a Virus. Any time you want or need to check for upgrades, go to the web site of the True Owner of the program in question. For example, to check out Firefox, go to Mozilla.org. {web link}

You can also report such a site at; Google Report Phishing Page {web link} which is the same when done while on site by going to Help > Report Web Forgery

If you use Firefox's Library dialog (Ctrl+Shift+h) can you spot any pattern to the events leading up to the fake warning?
