Does the job!

Super

Nice

Could you provide info on what is collected by you on users? There are files in the addon loaded from your website(s). Is this necessary?

I downloaded the add-on based on popularity. It did not detect the video on twitter. Nor does it accept suggestions as to where the video frame is.
I suppose it is Windows oriented (I use it in linux).

Does exactly what I need it to, with no problems whatsoever. Probably my favorite Firefox extension!

Thanks

Fonctionne a merveille, je recommande.

This extension is very efective.
Thank you.
