Simply amazing, the bad reviews seem by people that do not know how to use the plugin and/or read the help section :P

Всё заработало. Расширение - пушка! Без проблем вырезал надоедливую рекламу с сайта. Если хотите запускать скрипт на всём сайте, то используйте ссылку формата https://example.com/*

Not sure why it got poor reviews before, it's a very handy url filtered javascript injector that works just fine, better than most of the others as they run on all pages
