hi, we think this is caused by malvertising (malicious ads on otherwise legitimate websites). as long as advertising networks are out of control you might want to consider installing an adblocking addon: I found a fake Firefox update

Does this have anything to do with my computer at all or I shouldn't be worried about it?

And how long has malvertising have been around?

Hi, no it's not your computer. This surfaced in a big way around the middle of last year.

If you are in any doubt about the authenticity of update pop-ups etc., it's always best to ignore them and check for genuine updates 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.

We are trying to find a permanent fix, but it's proving very difficult. A possible workaround which seems to be quite effective, 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

People are welcome to discuss the subject of the fake urgent Firefox update page if they have some input on where and how and such on how this is occurring so Mozilla and others can get this whole thing shut down if possible. The fact that they are still targeting Chrome users (on Windows) also and even perhaps have a fake Adobe Flash Player page shows they may not be easy to get rid of.

The issue I have is the thread is only for discussion of useful things about the one fake urgent Firefox update concept and that people not talk about fake Mozilla and or Firefox download sites in general as they should create a new thread for those. Pretty much everybody gets that however one rude person tried to hijack the thread sometime back as he thought a well known official *.mozilla page was somehow fake or spoofed and he insisted the thread was about fake Mozilla sites in general even with a few people telling him otherwise.
