The newest version of Firefox added browser.ml.linkPreview.* settings in about:config, which apparently serve no purpose other than popping up massive, stupid overlays where they offer to use AI to describe the bookmark you've visited 500 times.

So fuckin' stupid that we have to constantly disable more and more settings they've randomly added to get around the fact that we've disabled all the settings. It's just the fucking worst, people that run companies are all brain-dead assholes.
