Firefox 56.0 running on Mac Sierra 10.12.6
After clicking on a car during the race, the viewer doesn't center itself again once I press esc. It kind of stays in the same position as it was when it was last following the car. There is no way to pan or move the viewer manually so you're then left with seeing only a portion of the track. This has only happened once or twice before today. Not every time.
Okay, I've let the developers know about this. Thanks!
