[Was] The best of many YouTube sidebar removers I've installed most recently. Does not break YouTube as do others I've tested. No more distractions! Unfortunately I cannot find what if any privacy concerns exist in this add-on. Removed stars since I do not see a developer link disclosing a privacy policy.
UPDATE: AdBlocker Ultimate breaks this add-on and at least one other. Just an FYI in case anyone using AU says this add-on doesn't work
