uBlock Origin + webannoyances
uBlock Origin has been my favorite plugin for a while now, but I generally haven't dug into it to try and become a power user. I also largely haven't needed to since it "just works" out of the box. There's a nagging sense that some things slip through the cracks like sticky footer popups and intrusive modal email popups, but I didn't care enough to do anything until Google released their godawful "log in with Google!" animated popup a while back. Overnight websites that I loved became an infuriating whack a mole.
Luckily I came across webannoyances. It's a project to enhance the default uBlock lists, and it works a treat. I've been using it for several months now and am a fan.
