Qutebrowser and (maybe, haven’t tried) Falkon can use qtwebkit as a backend
luakit, surf, otter, epiphany, badwolf, vimb use gtkwebkit
lynx, links, elinks, w3m, netsurf use their own browser engines
there’s also 😒 f*refox 😒 and its forks, if you need cancer like css, js, webrtc, or wasm
My favorite is when characters in the game use profanity but trying to use the same profanity in chat gets censored
