It works.
No more youtube cards in the end of the videos obstructing the last seconds of it.

For some reason, my antivirus claims this is an "unreputable add-on", but it works flawlessly for me with no issues.

Danke. Diese scheiss Karten haben mich schon jahre lang genervt. verstehe nicht wieso man diese crap-funktion nicht ohne addons ausschalten kann

Doesn't work, just stops the video short of where the cards would appear.

Works perfectly with /Działa znakomicie z/ Firefox 62.0.2 64bit.

this doesn't work. i still get the youtube cards and the end of the videos. i wish i could give no stars for this

worked perfect.
thanks!
