After a bit of messing around with why blocking auto play of videos is not working, i managed to find a work around and stop videos from auto playing.
Only by disabling my extensions, ublock origin and no script, i could get brave to work as intended and it would stop auto play of videos.
1.Disable my extensions
2.Open youtube, select a video,
This even works when i have someone’s channel open and i open one of their videos in a new tab,.
Enable my extensions and youtube videos will revert to playing and ignore the “enable block auto play”

Why would then, extensions be effecting braves settings this way
