Seamonkey: How to watch Youtube video the old fashion way

Youtube is now using html5

This is great obviously, because it means by default the internet browser doesn't need any plugin.
But let say you want to read your video the old fashion way using adobe Flash
well you actually can ... just by adding the url &nohtml5=1

for example:
https://www.youtube.com/watch?v=4h_OSURFicY&nohtml5=1

This will open the video and use adobe flash (instead of html5)
if you are not sure - just right click on the video and you should see this:

Seamonkey: Enabling full-screen for Youtube video

Seamonkey default settings

For some reasons the internet browser Seamonkey decided to prevent people to open full screen YouTube video - maybe they were tired of complaints of user who couldn't not exit the video (by simply pressing Escape?!)

Anyway now by default the full-screen button on the lower-right is disabled.

Overriding the setting

in the url path type: about:config then confirm that you know what you are doing

then look for full-screen-api.enabled and set this to true

That is it
