Privacy concerns

Stay away from this extension. Stylish collects EVERYTHING the user does and sends it to their servers. See https://robertheaton.com/2018/07/02/stylish-browser-extension-steals-your-internet-history/ for a breakdown and more information. This add-on needs to be pulled as soon as possible!

Stylish collects and transmits all your browsing behavior over the internet in order to analyze and sell this data. Have a look at 'Stylus' which is a fork of stylish without the invasive privacy infringements.
