Everytime relatives share me their facebook links, I get reminded how bad the facebook web site is.
There's full page banners upon banners reminding you to log in before showing the 2- /5- /7- /20- second video. Some videos play automatically after the target video not even allowing you to replay the original if you missed something. Endless hours of engagement~!
But expect a LOT more of this to come. A lot of sites already break on firefox just because various things are sandboxed. But there is active incentive for them to disable themselves to switch people back to Chrmoium
