Fake malware, please do not open or run that file. More info to follow

Hi sseagrave, Thanks for reporting this, as you guessed this is fake. Firefox does not do updates that way, and nearly all the official sites and pages contain mozilla.org Your screeenshot seems to have gone astray, could you try to attach a screenshot again please, there is a button for that under where you type. *[[How do I create a screenshot of my problem?]] Note it will need to be a smaller type of file, such as .png types that the Windows snipping tool creates, or a .jpeg type file. (Large bit map file types that may be sometimes be generated by using the Print Screen won't upload). This malware uses personalised links, I am unable to see the site or the download you link to. Does it show what the file name and type is ? is it a .exe or a .js file. You may be less likely to see such fake updates if you use a blocker such as ublock origin * https://addons.mozilla.org/firefox/addon/ublock-origin/ At present I am waiting for feedback from Mozilla staff.

Here is the image you requested as a JPG.
