No idea who this will be useful for, but starting with FireFox 49 I have
been running a modern FireFox with CentOS 7.
I needed to in order to play with the new Service Worker based Push API
but it has other things FireFox 45 ESR doesn't have - such as working
html5 details/summary tags - which I make us when a page needs a Table
of Contents, for example.
Anyway I start with Fedora src.rpm and build it in mock on my system.
Here are the changes I made to Fedora spec file for FireFox 50:

nss in CentOS is too old so that has to be disabled.
Hardened build works so I change the detection macro to trigger
The UA patch I disable for privacy reasons. Including the distribution
does not convey meaningful information to a website, it only adds a
characteristic that helps with fingerprinting. So I don't apply that
patch, X11 Linux in the UA string is enough information on its own.
Hope this is helpful to someone, but of course remember that when CentOS
is using an older version, you won't benefit from security patch updates
to CentOS. Have to watch Fedora to know when its time to download
another src.rpm that includes the fixes. So only use this over CentOS
FireFox if you really need it.
