Great extension, I've been using it for years. One recommendation for the next update: It seems to not detect the URL changes on single page apps, like Twitter for example. So if the script does not fire on the first child URL visited on a specific domain, it will not fire throughout the whole SPA, no matter the trigger URL is visited later.
Есть возможно как-то делиться скриптами? Если нет, то хотелось бы увидеть в след версиях
extension site needs full dark mode. also seem to be having an issue with removing a site from the list. useful extension and looking forward to updates.
Добавьте отдельно предзапуск яваскрипта в начале страницы, чтобы не ждать исполнения всей страницы минуту
내가 이런 리뷰 잘 안남기지만 이런 유용한 확장 프로그램에 추천을 안할수가 없네요. 과거에도 비슷한 기능의 확장 프로그램이 있었는데 그에 비할바가 아니네요.
Tried 4 other extentions before. This worked
Спасибо за предоставление такого замечательного инструмента! Было бы лучше, если бы страница автоматически обновлялась после изменения статуса правила.
This is so much easier and better to use than Tampermonkey. Thank you! By the way, the donation option might have issues when trying to pay.
Ohne zu wissen dass es bereits existiert, hatte ich überlegt etwas Ähnliches zu entwickeln. Diese Extension erfüllt aber bereits alle meine wichtigsten Wünsche. Fantastische Arbeit! 👍 (Das Teilen von Scripts wäre noch gut, verstehe aber dass man das evtl wegen Sicherheitsbedenken oder/und Moderation eher lassen möchte).
Wonderful implementation.
