Suddenly Firefox has randomly decided that it will no longer play any videos anywhere ever. I have changed absolutely nothing, videos just fail to play at all. Every solution that exists on the Internet has failed to solve the problem. And I do mean EVERY solution. I can open the exact same video on Chrome and it plays immediately with no issues. The app is simply broken. Very cool. I love it when software stops working due to no fault of my own and nothing I do fixes it. Glad I spent two hours on that.
