Minimal and fully functional!
Probably one of the most handy tools I keep forgetting I have installed! I've used it in a few different places to fix small personal-preference related issues across the web and it only takes a few minutes to "set and forget". My favorite use so far has been to remove the stupid ad banner that shows up when I log into a certain online payment/peer-to-peer payment site that won't be named. Not only did I hide the banner, but I also added a tiny javascript snippet to automatically redirect me to the dashboard once the page finishes loading. No more clicking to continue!
Great tool. I use it constantly
This is one of my favorite Chrome extensions. Highly recommended if you know basic CSS/Javascript coding.
Great extension! One thing I find annoying is that you can only have one script per domain/url. I want to make modular scripts for all domains that can be turned on and off.
Excellent et fiable.
Très simple à utiliser, fonctionne parfaitement :)
how to insert babel?
超Nice的一个扩展 👍👍👍👍👍👍👍❤❤❤❤❤❤❤❤💖💖💖💖🌹🌹🌹🌹🌹👏👏👏👏👏👏
Exactly what I needed. I previously used different extensions for CSS and JS, and this one could replace them both. Thank you!!
