Hmm, it seems to include its own jquery file? Seems to rely on jquery a lot, even in the css/js injection part of the script. Uninstalled. Devs, please let me know if I am wrong.
Great
Awesome – the best custom CSS and JS injection tool yet!
Excelente!!!
Support for chrome:// URLs would've been neat, other than that it's 10/10
Skvělé udělátko! :-)

Just. Perfect.
Deserves.
