包含脚本到页面

Question

I am trying to include script to any client's page. I create firefox extension which find tag and appendChild there with my script. And that works fine. And it works when client use http pages (It load properly and execute) But that doesn't work when client use https pages (it load properly but not execute).

I have the same code for http and https. In my code I haven't special http and https conditions. Anyone know what can be wrong ?

I think code is ok, but ok, examples:

Injecting script (in extension):

   var myScript = top.window.content.document.createElement('script');
   myScript.type = 'text/javascript';
   myScript.setAttribute('src','http://path/to/my/script.js');
   myScript.setAttribute('onload', 'firefoxInit()');
   top.window.content.document.getElementsByTagName('body')[0].appendChild(myScript);

Code to execute:

var manipulate = (function(){
   alert('duper execute');
}());

https will not let you run insecure content like scripts from a non-secured url, so your http-hosted script.js won't be allowed to run. Mixed content is blocked by default in the current versions of Firefox and Chrome (not checked IE)
