Это пушка! 5 баллов! Пользуюсь каждый день для диких javascript-утех, работает как часы! Честь и хвала разработчикам!
quality app for implementing custom stylesheets or js code on sites i frequent
Excellent extension with loads of extras to help developers, including some hidden features like Ctrl + click for multiple cursors, Alt + drag to highlight a rectangle, etc.
Awesome extension! I am a web developer & i use it daily in many sites to: * Extract information to the console * Extract information to the page (when the information is related to some elementos & i want to see the information in its context) * Modify the look&feel of the pages * Trace events to validate them * ... With some knowledge of JS & CSS you can do almost whatever you want 🤩
This is awesome!!

Hasznos jószág, ha valaki ismeri a javascriptet.
Love it, it only needs some autocomplete features and it will be complete
This is an awesome plugin. Thanks.
I was looking for tool to inject some code, "side wide". Finally found.
