Great work. Increases my productivity drastically. Is there a way to run multiple scripts in a specific order. For a given site I want to write a base script that will always load first (for all pages) Then based on the specific page additional scripts will be provided. Thanks
Amazing and powerful to make other people work better.
This is literally the best extension for adding custom javascript or css to a website. Also great for prototyping your own extension or starting to build your own website widgets. It does make finding issues for clients websites easy as well because I can debug their javascript easier just using this extension and going to their website. Love it.
Very recommended. It is very easy to use and works perfectly on both Google Chrome and Microsoft Edge.
This is by far the best of its kind. Well done sir.
Лучшее в своём роде. ---------------------------- пользуюсь 4 года, всё супер.
Отличное расширение, благодаря которому настроил под себя множество страниц. Жаль не умеет в scss, но в целом отлично.
Крутое расширение. Спаситель нервных клеток. Один вопрос, можно как-то сделать чтобы после редиректа (window.location.href = '...') тоже активировал скрипты/стили?
perfect !
A very well refined solution to injecting JS and CSS to improve tools you use. This is something I rely on to improve productivity and fix the problems with web apps that move too slowly or are not specialized enough for my needs. The intelligent URL matching and ease with which you can export code, toggle features on and off and even the code editor are all very well done.
