I keep getting a message to update to 50.0.2 but I'm already on 50.1.0 (and it doesn't do anything when I click on the restart selection.)
I'm on a Mac, running OS Sierra. Every time I open Firefox I get a Software Update screen that says Update Ready to Install, 50.0.2, but I'm already running 50.1. I've tried trashing the version and reinstalling but I always get the message.
