The videos do not play on Firefox. However, they do play on Chrome and Safari on my MacBook Pro. Am I missing something?

They play perfectly fine for me in Firefox (v52 ESR). It's likely you have one or more extensions that are preventing the player from running.

For me Firefox won't play the embedded Vimeo player, but I can simply click on the button in the top left corner and it takes me to the vimeo website, where it plays just fine. It might be the same for you as well. Of course, if you use noscript you will have to figure out which script to allow or else vimeo won't work at all-- but then, if you use noscript you should know this already.

OK, I think I've figured out the problem. It's not plugin or extension related. It's a privacy setting. If you have Firefox set to refuse third-party cookies, the videos won't play on http://sfdebris.com/ , but they'll play fine on https://vid.me/ because they won't be considered third-party any more. For some reason this doesn't effect Chrome when set to disallow third-party cookies. Simply adding an exception for http://sfdebris.com/ to Firefox's privacy settings should fix the problem.
