Unbelievable addon！I have only two suggestions
1. the clicked urls（i.e a:visited）could be different-colored from normal urls（i.e a:link）, it really helps .
2. large white images could also burn our eyes , so img could be added an opacity value to make it not so bright , until the mouse hovers on it then set the opacity 1.

good

Makes loading of certain sites load EXTREMELY slow, such as reddit.com, when enabled on such sites.

It's absurd how good this add-on is, it lets you dynamically adjust the look of sites and does a great job. It's basically "one theme to rule them all".

Amazing work devs!!

Works really great most of the time, good enough otherwise. Eats CPU time, enormous amounts. Worth it, anyways.

very good.
