It’s really depressing how often I have to turn off CSS entirely just to view a webpage. I could of course always go into the inspector and turn off the bad CSS, but Gecko-based browsers fortunately have “View -> Page Style -> No Style” which is must easier and faster.
And seriously, whoever invented the font-weight CSS property can burn in hell. Ditto for whoever decided that we should only be allowed to read light grey text on slightly lighter grey background.
