+        Runs correctness test suites on Linux and Android emulator platforms, as

+        used to end up looking like a "F" shape (not so much these days) and so
+        this is typically referred to as an F-push. This is useful to do as a
+        general sanity check on changes to cross-platform Gecko code where you
+        unsure of what tests might be affected. Linux and Android (emulator)
+        test coverage are relatively cheap to run and cover a lot of the
+        codebase, while the builds on other platforms catch compilation problems
+        that might result from only building locally on one platform.
