I inserted a link about a post in Twitter, text can be seen, but for the video a message says "the video cannot be read".
I have extension s9e/mediaembed installed.

I have message:
extension cannot be activated.
Every validated extension has its own dedicated support area in our Customisation Database. It'd be better if you could post your question there, as it would also notify the extensions's author.
I think problem is somewhere else.
On my PC I have a copy of my board locally installed.
I uninstalled and deleted data of S9e media extension.
Installed and activated phpBB Media Embed PlugIn.
Problem is still there: "Video cannot be read".
Edit:
problem comes from Mozilla Firefox. I don't know how to fix it.
