Hello. Good extension. Working like vpn w/o questions, but starting with version FF 59.0.1 there are a lot of sites with artefacts of viewing pages when this plugin has enabled state(even not working) . For example, i see this fact on web-interfaces of my web-mail (mail.ru) or on the site of book shop (belygorod.ru) and others.... After a disabling this plugin and restart browser, all problem pages become good-looking. Author, please debug this.
