No it is not legit. The fake updates exe can install things like trojans, viruses or unwanted software based on past reports.
The desktop Firefox is not just for Windows as it is for Mac OSX and Linux also so .exe would not be an effective way to send out Firefox updates. The updates are done internally in Firefox with a .mar file or by download from mozilla.org like say www.mozilla.org/firefox/all/

Urgent Firefox Patch Download
According to the Sophos Naked Security blog machines infected in drive-by downloads from compromised sites receive the scareware that appears as urgent update notifications.
The clue that the updates are phony is that they appear only when the affected computer uses Firefox. Legitimate updates come via Internet Explorer, Sophos says.
Victims click to receive the urgent updates and their computers are infected with malware that seizes up the machines. A persistent popup says the infection can be cleaned up by buying anti-virus software - a phony product sold by the criminals behind the phony Microsoft update notification.
Sophos recommends accepting updates only from vendors from whom users have requested updates.
