462238 - Error: Permission denied for ... to get property Window.document from <moz-safe-about:blank> after giving universalxpconnect privileges

Status: RESOLVED WONTFIX

(Core :: DOM: Core & HTML, defect)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, you can test it online if you have the signed.applets.codebase_principal_support pref set to true.
You need to have to have the 'Show windows and tabs from last time' option set.

To reproduce:
- load testcase, then close Firefox and restart.

After restart, the designMode iframe is not editable and I see this js error in the error console:
Error: Permission denied for <file://> to get property Window.document from <moz-safe-about:blank>.

I got a similarly bogus error saying:

"Permission denied for <http://localhost> to get property Window.document from <http://localhost>."

I've tried to produce a minimal testcase, but that hasn't worked out so far. I'm using an iframe in designMode, and everything works fine except when Google's jsapi is loaded from www.google.com , which seems to trigger overzealous cross-domain restrictions (but that's just my guess).
