uBlock Matrix is good too, if you want to manage all the things. You basically white/blacklist all the image, css, xhr, etc. requests on the page and can set up rules like allow iframe from youtube.com on all sites, to allow the embed youtube frame to show up on pages. Many sites are broken on first load until you get your rules straight but they're trivially fixed. You just click on boxes to allow or deny the particular thing.
