The best code injector I know of.
So many similar add-ons only inject CSS or JS, but not both.

This is a great extension, but won't work with restrictive Content Security Policies, which is fair enough; that's why they've been implemented.

Nice

Doesn't work, cannot inject code into iframes.

A no-nonsense code injector that works like a charm.

Can i save profile using domain ?
like now open website domain A.com code injector view list only script for domain A.com

Handy tool!

Best injecting extension i've found yet! thanks for this awesome work

Awesome code injector. But I'd appreciate if there was some option to either lock the popup window so it won't close when I navigate or reload the page OR if you could open the popup in a separate window.

The best of the best, there is no better alternative outthere
