Is there a Whitepaper or similar which describes how the automatic updating of Firefox is secured?

more options

I'm facing an Audit from our Security which is asking how the automatic update process of Mozilla Firefox is secured against Manipulation or malicious Software. The fear is that per example somebody could manipulate the update to load an infected File instead of the original Firefox Update. I've already searched for half a day through the Internet and in the Mozilla wiki but could not find a description of this. Could you please provide me a Whitepaper or similar which describes how Mozilla Firefox ensures that only official and not manipulated Updates can be loaded and installed e.g. does the Client validate the installer hash before execution etc.

Here would be the equivalent Information from Google about Chrome:

All updates come from and only contain the program in question.

Sorry for my bad english i'm not a native english Speaker.
