This extension blocks CSS, which is ugly and slows the internet down,
Almost all websites send nearly useless and often dangerous css-files to their users just to add flashy visual effects to a website. Not only does the CSS-code itself use up bandwidth (700Kb with more than 6000 rules on facebook), but CSS itself can load additional resources, like fonts, images and vector graphics. It can be used to hide and obscure content.
To stop this needless madness, we've created CSS-Block. Just install it and all your worries are gone. No CSS file will ever be able to bug you again.
