Running Tor Browser unit tests as part of our gitian-based build process
The Tor Browser patches add or modify some unit tests. Running those tests as part of the normal build process would allow us to test the main Tor Browser features using the same binaries that we ship. Running all Mozilla unit tests as part of the build would take a lot of time, so it's better done using Mozilla Try, but if we limit that to the tests that we add/modify, the time to run the tests is probably more reasonable.
