Again the issue of Firefox enforcing content-security policy on websites ... see also Bug 411148

I understand it's not a KDE issue but is there something to be done about it?
I tried disabling CSP but it didn't help

The player detection code could be injected in such a way as to not trigger content security protection, as was done with the Audio constructor. However, for calling methods on the player, such as play() and pause(), I still need to dynamically inject code. I am not sure if that can be done with the exportFunction approach but I also haven't really looked into it.

Media session API (i.e. album art et al) isn't working either as a result of content security policy but that would be quite a hassle to get working, so I'd rather not). Media controls seem to work again, though.

Thank you, it works.

How soon will there be an updated XPI file to include this permanently?

We just found a way to even get media session (i.e. album art and what not) working with Spotify on Firefox. I'm planning to get a release out by end of next week
