I would like to report this add on. For being awesome!!! Works perfectly to eliminate sidebar 'suggested' videos. Theater mode wasn't cutting it. The distracting suggestions would still show up esp if/when the controls mysteriously vanished in theater mode and had to revert to normal mode...thus seeing the rabbit hole distractions again. So far so good. Thx
UPDATE: AdBlocker Ultimate breaks this add-on. Just an FYI in case anyone using AU says this add-on doesn't work
