ottimo elemento

The auto-pause feature doesn't work. Meaning, it does pause the video at the beginning, but very frequently doesn't let you resume the playback, pausing the video again. A very useful extension that doesn't work. But in FF versions 52.6 & 57.

Generally good, and I like the black background option in YT. Options selected from the YouTube screen work as expected, but not from the red HD icon in the add-on toolbar.

A very good extension, I like it.
