Embedded twitter The media could not be played Fix

[Frank Lion]

Thank you.
And especially thank you for posting a solution

No problem.

One picture is worth a 1,000 words, etc. Don't bother thanking our in-house AI unit, it won't understand it.

Not sure if you'll answer but Frank, would you mind if I asked about your claim to fame?
Are you a Firefox developer... associated with Mozilla itself, or maybe this forum? I know people know you here, but for us outsiders...


Twitter videos are not playing in the about to be made public Firefox ESR 52.5.3 and by extension I assume also Fx 57.0.3.
So it looks like the earliest this gets addressed is Fx58.
Or maybe we'll get confirmation this is all by design and will never be addressed, I would welcome that news because I would just redo all Firefox images on family's computers with Gingerbread Man's fix, just don't want to go through with the effort if it'll get addressed in Fx58, but on the other hand, Fx58 is almost a full month away, Jan 23, 2018...

I have no idea what I'm doing wrong with the header editor, it's still not working. :/

I exported the rule and this is what it shows, where am I going wrong?

Code: Select all

{
	"request": [],
	"sendHeader": [
		{
			"enable": 1,
			"name": "Twitter",
			"ruleType": "modifySendHeader",
			"matchType": "prefix",
			"pattern": "https://twitter.com/i/videos/tweet/",
			"exclude": "",
			"isFunction": false,
			"action": {
				"name": "content-security-policy",
				"value": ""
			},
			"id": 2
		}
	],
	"receiveHeader": []
}
