As of last night, without warning and without me changing any settings, or restarting my computer, when I go to open Candy Crush (on Facebook) the loading process freezes and I get a banner at the top of the screen telling me "This page is slowing down Firefox. To speed up your browser, stop this page." At that point I can close the banner, or stop the page, but either way no further progress is made and the page seems to freeze. Candy Crush will still run on Edge (which I would REALLY rather not use at all!!!!). So this is a Firefox issue. Please tell me how to fix it.
