Bug 1540573 - p7. Modify CSP tests to use preload=2 on (emulated) cellular connections. r=jya The Content Security Policy tests were handling the smaller android preload values that were #defined on Android by setting media.preload.default=2. Now that we're detecting whether we're on cellular or not, and the android emulators that our tests run on emulate a cellular connection, just setting media.preload.default is no longer enough. So set media.preload.default.cellular=2 in the CSP mochitests instead of media.preload.default, to make the CSP mochitests pass in the Android emulators. Differential Revision:
