Is this a legitimate patch; firefox-patch(1).js from eutaedom-filmov.org?

I have received this update notice the past week when I close Firefox and, although it looks legit, I am hesitant to install it because of its source.

It sounds like you got a random weird name website claiming to have a urgent Firefox update and serving a fake firefox-patch.js file.

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, or unwanted software on Windows based on past reports if the user runs them. Mozilla has no need to host Firefox downloads or updates elsewhere, especially not at random weird name websites.

The way Firefox updates are done has not changed as updates are done internally in Firefox (with a .mar type of file) whether on Windows, Mac OSX or Linux or by download from mozilla.org like say www.mozilla.org/firefox/all/

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 a few months 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

Hi, no Mozilla Firefox doesn't issue updates in that way. It's a fake update scam designed to infect you with malware! NEVER EVER click on anything like that! Please see the article - I found a fake Firefox update.

If you are in any doubt about the authenticity of update pop-ups etc., it's always best to ignore them and check for yourself by opening the 3-bar menu > Help (question mark at bottom right) > About Firefox. Alternatively, you can press the Alt key to bring up the main menu bar > Help > About Firefox. More - Update Firefox to the latest release.

A possible workaround is to install an ad-blocker, such as -

Or, but this may be less effective - https://addons.mozilla.org/en-US/firefox/addon/adblock-plus
