Hi,

In a couple of weeks, Tor Browser version 15.0 will be released.
I'm already testing the alpha releases. While running the first alpha
release, I noticed that it didn't "look" like Tor Browser but like
Mozilla Firefox (in terms of the browser name, logo and some other
things).

I did some digging and I found
https://gitlab.torproject.org/tpo/applications/tor-browser/-/work_items/43772#note_3240223
The summary is that for Tor Browser, --enable-official-branding
should not be passed to configure (anymore). However,
mozilla.port.mk passes that to every port that uses mozilla.port.mk.

There's multiple ways to make sure we don't pass this flag to
the Tor Browser port; below some ideas:

1) surround "CONFIGURE_ARGS += --enable-official-branding"
in mozilla.port.mk with a check to see if we're building Tor Browser.

2) move "CONFIGURE_ARGS += --enable-official-branding" out of
mozilla.port.mk and have every "official" Mozilla port (i.e., every
mozilla.port.mk port that is not Tor Browser) specify
"CONFIGURE_ARGS += --enable-official-branding" itself.

3) surround "CONFIGURE_ARGS += --enable-official-branding" in
mozilla.port.mk with something like
".if defined(MOZILLA_ENABLE_OFFICIAL_BRANDING)" and set it in
every mozilla.port.mk port that is not Tor Browser.

4) the same as idea 4, but something like
MOZILLA_DONT_ENABLE_OFFICIAL_BRANDING which is then only set in
the Tor Browser port.


Maybe there's other (better) approaches that I didn't think of.

Below is a diff that implements idea 1. What do you think? Do you
like another approach (e.g. idea 4) better?

Thanks,
Caspar
