1 star, after uninstall videos still open in cinema mode

Doesn't work anymore. Apparently it was updated today (June 29th), so perhaps something broke.

I M P O R T A N T !
WRECKED [Full Screen] mode (not filling entire display).
Wrecked Player mode settings. Always switches to [Cinema] mode & always resets player's speed to [Normal]. WRECKED, because changed browser's preferences permanently,
_even after disabling and uninstalling extension_ browser now always start videos in [Cinema] mode & resets speed to [Normal]
Lacks option for disabling automatic switch to cinema mode. I would like to decide myself which video in what mode to watch.
Resuming I must say the extension behavior is HARMFUL!

no longer works

doesn't work with firefox quantum
