Problem of Signing html files

Hello,
         I am trying to access scripts in the chrome registry from my html files on the server. I get an error of Universal XPConnect privileges denied. I am creating xpcom components in the scripts.
         If I have a lot of html files which require this functionality I have to place all of them in a signed jar which I think is not feasible. If I have asp or jsp on server side which create html files dynamically, I cannot sign that html content. Is there any workaround.
         I know if we change the prefences on client side then it works. The preference is as follows. 

         pref("signed.applets.codebase_principal_support", true); in the browser_pref.js.

        Without adding the above preference, is there any solution.
