For newer versions of Chromium and Firefox, support for NPAPI plugins is disabled/removed, so there are only 2 options, HTML5 and protocol/external video player.
Can't play any video
I'm on a web browser who can't play youtube video by default (Abrowser), i have only the sound with a black square. So i tried your extension to solve it, but it made it worse: the video doesn't even start and i have an error message: "ViewTube Couldn't get the videos content. Please report it here."
I've committed an update, tested a few videos with the login creds from bugmenot.
Thank you. A few notes: Previously when the videos were still on rtlxl.nl there was a requirement to login too. ViewTube didn't seem to care and created the element right away without the need to logon. Is it possible to have the same behaviour? Also, the original player isn't removed. Other than that everything seems fine.
Updated to work without login. Tested in Firefox and Chromium.
What do you mean the original player is not removed?
I don't know what happened with the last version, everything works fine now. Thanks!
