It's an infected ad offering a false Firefox update which is in fact a malware. Don't download it and if you have downloaded it, don't execute it in Windows.
is there a way to keep it from recurring on my computer? thanks
Nope, it's offered by some ads hosted on variou websites. The websites should fix the issue with the advertising companies they use.
On your side, if you are using an AV with virus definitions up-to-date (like Microsoft Security Essentials) and you download the malware accidentally, the AV should remove it.
If you mean you are getting a random name website page claiming to have a so called urgent update for Firefox and a prompt to download a fake firefox-patch.js file. The random name of the website alone should raise a flag that it was not legit.
This is not from Mozilla or the Firefox web browser. The fake firefox-patch.exe and firefox-patch.js files can install things like trojans, viruses, unwanted software or to download additional stuff onto Windows based on past reports if the user runs them.
You could try using a adblocker extension like uBlock Origin to block theses fake ads if you keep getting them. https://addons.mozilla.org/firefox/addon/ublock-origin/
Unfortunately this has gone on for several weeks now with one or two new sites reported almost everyday. https://support.mozilla.org/en-US/forums/contributors/712056/ and https://support.mozilla.org/en-US/forums/contributors/712075
