If you have uBlock Origin - and who doesn't - you can use the 'element zapper' to do targeted killing of such annoying elements. It does wonders for those sticky headers, grey-out overlays and similar nuisances. Bind it to a key - I use CTRL-ALT-Z for 'zap' - and you don't need to leave the keyboard to go on a killing spree.
