I would like to modify a chrome extension for personal use. However, I have not been able to install it satisfactorily.
When I use 'load unpacked extension', my browser warns me every time I launch that I am using developer mode extensions. If I pack it and install it, I get the error 'this extension may have been corrupted' and cannot enable it.
I have tried removing the 'key' from the manifest.json and updating the version number, but still get the corruption error. What do I need to do to prevent this error from coming up?
Edit: I tried hosting it on the Chrome Web Store under private visibility, but when I try to install it I get 'An error has occurred: Access denied'.
