It still shows and that's expected behaviour.
What does "R" button do?
Any spacebar updates? For me it still does not work.

Your Firefox has the Pointer Lock API disabled by preference ("Request for pointer lock was denied because Pointer Lock API is disabled by user preference"), which is why mouse look needed the right-drag mode. The google-analytics errors are just your tracker blocking and are harmless.
