  • (2021-12-07) Mustafa: ok but how can i use the HTML editor, i mean how to edit a specific area in the weppage using this extension
  • (2021-11-21) Thor Galle: 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.

  • (2021-02-22) Danny: Really cool features for injecting code
  • (2020-09-30) Андрей Камышников: it working for me! Спасибо!

  • (2020-10-23, v:0.3.2) Rex Gsman: Can't load files from local Drive on iframe.
    Your extension is fantastic! I'm loving it! However, I can not make it work as fine as I need. I'm injecting an iframe with a .html file from my local drive on it. It works great except that it doesn't load the file from my local drive. I made few tests and it only load files when they are from https URLs. It doesn't seems to load files from http, or file:// URLs. This is my code for the iframe: <iframe src="file:///C:/mynotes.html"></iframe> It works great on a regular html document, but not on your extension. I can not find any possible solution, no matter how much I try. Is there any way to solve this? Thank you very much in advance.
