Really useful and cool extension!
Awesome, it works great! Thank you <3
Why do I have to reload the page every time I visit it for the CSS to load?
Beautiful, free, powerful, SASS support, the best of it's kind!
I just love it! Thanks for the awesome extension in terms of UX and functionality!
Awesome extension! Love the combo of JS and CSS/SCSS both in one + the nice dark themes. 👌 Just one question out of curiosity: Is there any performance impact (positive or negative) when enabling the "Isolated Environment", maybe due to some overhead or similar?
You can create multiple JS and CSS scripts for each website and name them, toggling them on/off as needed. Text editor is color-coded and easy to work with. Super useful for anyone who knows a little code and wants to customize their browsing experience.
Отличное дополнение в своей категории.
