Similar to Stylish, this extension allows you to change the appearance of a website on your side. However, unlike Stylish, this extension does not track your browsing history. Stylus, rather, has the features of Stylus, without collecting your history and sending it to a third party.
Rather than just simply changing a certain website to black and white, the possibilities are endless due to the extension’s massive catalog of user-submitted themes.
The Chrome extension can be found here.
