I can confirm that that picture:
https://i1.ytimg.com/vi/122yTyQguA4/hqdefault.jpg

is the beginning of the ad i get, if i for exemple unselect the filter
=adunit&

or related by it's visual content..

[delicacy]

The strings that are different in the loaded ad-like picture & not found in the links of the normal video picture id:

ad_to_video
get_video_metadata
https://www.googleapis.com/youtube/

https://www.youtube.com/api/stats

&cplayer=2
&format=2_2_1
&ad_sys=AdSense

[delicacy]

For
https://www.youtube.com/get_video_metad ... ubscribe=0

I tried to select/unselect those added filters without success:

||youtube.com/get_video_metadata?*
||googleapis.com/youtube/v3/videos?*
||youtube.com/api/stats/*
&ad_sys=AdSense
||youtube.com/csi_204?*

[delicacy]

I gave up &..

moved back to:

https://greasyfork.org/en/scripts/9932- ... ion=137947
the only actual script & version compatible with all firefox versions
that fix the ad issue.

since adblock filters don't fix it.
