Although I have succeeded in several extensions, I used the 4.2 version of CSInterface.js, but when I sent it to the expansion market, I found it only compatible with 18.0-20.0. I don't know why, after all, my code is very good. Simple, not too complicated, so I am looking for help, is there any way to test its compatibility before uploading?
I have used html5 and css3 in my extension panel. I don't know if it is for this reason.
