187976 - XMLExtras accessing remote resource fails even when UniversalBrowserRead granted (regression)

Status: RESOLVED WONTFIX

(Core :: Security: CAPS, defect)

Description

[Heikki Toivonen (remove -bugzilla when emailing directly)]

Use the testcase in extensions/xmlextras/tests/syncget.html from your local
disc. On opening it will ask if you want to grant UniversalBrowserRead - do so.
It should then get the remote resource, and display the responses.

What actually happens with trunk builds is that the remote resources are
retrieved succesfully, but serialization of the responseXML property fails
because of a security failure:

Exception... "Access to restricted URI denied"  code: "1012" nsresult:
"0x805303f4 (NS_ERROR_DOM_BAD_URI)"

This is a regression. This works in Netscape 7.x, for example. Does not work in
1.3alpha and forward, but I have not pinpointed when exactly this happened.

I found this out when working on bug 166978.

This bug has been tagged for regression and or closure.
UniversalBrowserRead - appears this functionality has been removed.
Is there any reason not to close this out? - if yes please provide updated STR
