legal question

Hello,

Company I'm working for is going to embed FireFox browser into their
commercial application.
>From MPL it's clear that this is allowed. But it's hardly possible to embed
FireFox browser to anywhere, because it's compiled this way.
So I have a question.  Is it allowed/permitted to build FireFox with
different compiler options and distribute resulting package with commercial
applications and standalone under the conditions below?

-all compiler options that will be changed are taken from Mozilla web site
-original sources used for building FireFox are left non-modified
-no additional sources are added to FireFox
-no additional extension are added
-copyright and other legal stuff (logos, tm) will remain untouched
-package will be made freely available online.
-package name will contain FireFox in its name (for example embeddable
FireFox or FireFox for embedding etc)
