Are you thinking it was from the Firefox web browser or from Mozilla simply because it had a big Firefox icon on page?

Anybody can create a page with a product icon and then serve a fake download and claim it was a update for said product. This has been done with Flash Player and Java plugins for a long while for example. The random name of the website for example should raise a big flag on its legitimacy.

Mozilla does have a legit new Release recently as Firefox 48.0 was released on Aug 2nd and can be updated internally in Firefox by checking for updates or by download from say www.mozilla.org/firefox/all/

This unfortunately has been going on for a couple months now as I added the uabeeprozdravi to the long list of fake sites at https://support.mozilla.org/en-US/forums/contributors/712056

STOP! That is a malware phish.

Mozilla has not changed the way Firefox updates: you would never get a popup emanating from suspiciously named website, you would never get a download dialog, and updates are never .js files.

Since these redirects seem to be triggered by ads on some websites, you might consider an ad blocking extension such as the following:
