signed.applets.codebase_principal_support is set true but I always get error like Error: A script from «https://127.0.0.1:8080 <https://127.0.0.1:8080/> » was denied UniversalXPConnect privileges.

On linux it works well.

May be I need to change something else ?

Possibly the consequence of this bug fix.

(please do not comment in bug reports)

I used it to access the system clipboard,and now I have to write this to prefs.js all by my self to ensure not to get this error. user_pref("capability.principal.codebase.p0.granted", "UniversalXPConnect UniversalBrowserRead"); user_pref("capability.principal.codebase.p0.id", "http://localhost:81"); user_pref("capability.principal.codebase.p0.subjectName", "");

What is the best way to access the system clipboard?
