Turn --enable-base-browser in --with-base-browser-version
The browser version customization might be needed for all our browsers (Tor Browser that has it already, Base Browser, and Privacy Browser).
I think it doesn't make much sense to have duplicate code for it and conditional code in tor-browser-build.
So, I'm more up for changing all
BASE_BROWSER_VERSION, and replace
--enable-base-browser with a
--with-base-browser-version option that takes an argument.
At the moment, we exit with an error if the user doesn't define a Tor Browser version, should we do it also for Base Browser? Probably it's a good idea, since we enable/disable stuff if it's defined.
Should we change
TOR_BROWSER, and then define
browser/config/mozconfigs/tor-browser and in
Or should we keep
TOR_BROWSER_VERSION as an alias of
