would be excellent but has a missing operation makes the funcionality very irritating, a whitelist not constant, if you choose "always enabled" in one site, and later restart firefox may or may not continue remembering that option, it's annoying,apart lacks options where show the whitelist and blacklist (eg youtube, that sometimes you have to re click activate always)

There is no whitelist, it's just a switch to enable or disable the click-to-play. The goal is to leave the click-to-play always on except when it breaks page functionality, you can then disable it for a short time (it resets on browser restart, that's what you experienced).
