I accidentally set youtube's HTML5 player to disable full screen - how do I re-enable it or manage my permissions for HTML 5 full screen video?

Isisombululo esikhethiwe

That appears to be stored as a permission.

You can open the about:permissions page via the location bar and select www.youtube.com in the left pane.
You will notice a full screen select with three choices and with Block currently selected.
You can set it to Allow or to Always Ask as you like.

Try to clear the YouTube cookies

YouTube may also be using local storage to store data.

I have this 'cookie' in local storage to set the volume level:

yt-player-volume: {"volume":100,"nonNormalized":null,"muted":false}

You can delete the webappsstore.sqlite file in the Firefox Profile Folder to clear all data in local (DOM) storage.

See also "Storage location and clearing the data":

Neither option works, unfortunately. Have already tried clearing cookies before resorting to the forum.
