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.
