While using a link from this website (, I get a fake Firefox Urgent Update popup.

For the last few weeks, I have been getting fake Firefox Urgent Update popups. Being suspicious, I just opened Task Manager and closed all my Firefox links; cleared my cookies; and, then, when I ran my anti-virus, it showed a clean scan. But, the popup is still a hassle.

After carefully noting what websites I had open when it re-appeared, I narrowed it down to the free web radio site that I use to listen to Blues. Here is the link for the home page:

Note that the popup does not re-appear when I have just the home page opened. Yet, when I click on the link to, "On Air Now Listen Live", in less than ten minutes the probe appears.

I also took a photo of the file download info and am trying to upload that photo to this message; however, it is taking a long time, so I do not know whether it is going to load (a photo in a jpg format). Anyway, here is the file information that shows up:

firefox-patch.js 3.9 KB - - August 17

Tonight, I wrote to the IT Tech group of the website, to notify them about the malware linked to their site. I want them to purge it so that I can safely use their services.

Anyway, I wanted to let Firefox know of my deductions and actions taken. If I can provide any other assistance, I would be pleased to help.

We're tracking those fake updates sites here:

Somehow the perpetrator is hacking advertising networks and websites are caught in the middle of this plague.

uBlock Origin is effective at blocking that exploit.
