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.

It definitely works.

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

I use this to create css and javascript hacks to all sorts of pages. I use it to zap away content I don't want to see, and also to process lots of data. It is real handy.

Feature request: a way to inject jquery easily into a page prior to loading your code.

I have made a JS code and so far it works like a sharp knife, so many thanks for you. I'd suggest for improvements :
1- enable paste option in the code area, you have included copy and cut but I can't past in it.
2- make the same function for android app, I searched a lot but can't find the same thing
3- make the file section more effective, instead of making the user write the pathway of the file, you add an option to select and upload
