First, is this a good discussion forum for uMatrix questions? Gorhill doesn't have one, and Reddit suggested here. Question: does anyone maintain a list of known whitelistings for popular web sites? For example, YouTube doesn't work unless you allow ytimg.com and a few google*.com domains. Ideally these would be minimalist whitelists, e.g. only allow the domains absolutely necessary for site to function normally, but leave extraneous parts (such as ads & trackers) blocked.
