Inject code into websites! (JavaScript, CSS, HTML and Files)
A WebExtensions based addon which let the user inject code into the websites. A very handy tool for developers and for automation.
This extension allows you to inject custom JavaScript code, custom CSS or even custom HTML to any web page.
Use it to customize appearance of a page, to auto-fill / auto-click forms on a page or to get rid of selective elements (e.g. advertisements) from a page. Get the control back on your browsing experience.
Backup / restore or share your rules using import/export feature (from Options).
Source code for this extension is available in GitHub, original work by L.Sabatelli.

- When looking at the Chrome Web Store, you may wonder why there are 2 extensions with the exact same icon and name available. From Github, it seems that the original extension by Saba (https://github.com/Lor-Saba/Code-Injector) was updated with a few minor fixes by Urmil Parikh (https://github.com/urmilparikh/Code-Injector/commits), and then re-released. I wish these authors could collaborate on keeping just one version in the store. This situation is confusing, and you could reasonably suspect that one version may be a copy with added malware, even though it is not the case, especially given the extension's broad permissions.
