After Stylish was sold at the beginning of 2017, the new owners partnered with a marketing and website traffic company. After looking at the updated code and found extensive tracking of their users, I quit using the plugin completely. See https://forum.userstyles.org/dis.... I switched to using Stylus (https://add0n.com/stylus.html); they aren't interested in my surfing habits at all.
