I have an add-on which about bookmarks and this add-on have ‘drag and drop feature’ in add-on page. When I change “security.csp.enable” in “about:config”, there isn’t any error.
But normally, when I want to run my add-on, console says “Content Security Policy” and this warn repeat the number of “ondrop=function()” and “ondragover=function2()” numbers.
So, my add-on is still review. How can I solve this problem?
