My honest reaction to your comment is "What? No!".
I want to block ads, block trackers, auto-deny tracking, download videos, customize websites, keep videos playing in the background, change all instances of "car" to "cat" [1], and a whole bunch of weird stuff that probably shouldn't be included in the browser by default. Just because the browser extension system is broken it doesn't mean that extensions themselves are a problem - if anything, I wish people would install more extensions, not less.
