jorge soares (ID: 000000ada21a6ff9) Voted 5 ★ - Updated 03/08/2022 After searching the net for a Code Injector, this one is the best! And it is free ! An improvement would be to incorporate by option, or by default, the link to Jquery. I can do this incorporation, by myself. Code Injector works very well. Congratulations to the programmers. I would gladly provide monetary assistance if offered that option.

Sam B (ID: 00000097274b6ca8) Voted 3 ★ - Updated 11/18/2021 It works, but unfortunately it does NOT inject the code automatically the next time you visit the site. You have to manually inject every time, which defeats the purpose of the whole thing. If code was open source on Github we could help fix that.
