This works very well in Firefox. A couple of observations, though. I'd like a Pause/Resume functionality. When I want to use Rakuten Cash Back shopping, for example, I'd like to pause privacy for a short session, then resume, rather than having to disable this extension in Firefox Add-ons. Ghostery and MalwareBytes have pause functionality. For the Oxford Dictionary extension pop-up, adding "lexico.com" won't work to allow it. The entry has to be "*.lexico.com". My other privacy extensions work with "lexico.com".
