2.) WebShell now implements the new nsIScriptGlobalObjectOwner.
3.) WebShell supports GetInterface to nsIScriptGlobalObject.
4.) Documents no longer carry around a reference to nsIScriptContextOwner. Instead they hold on to a nsIScriptGlobalObject. nsIDocument::GetScriptContextOwner has now become nsIDocument::GetScriptGlobalObject(). Same change to the set methods.
Add checks to nsScriptSecurityManager::CheckCanListenTo that take
a principal and ensure that the currently executing script code
either is from the same origin as that principal or has the
UniversalBrowserRead privilege enabled. (chrome code has all
privileges enabled by default.) It's okay for the principal passed in
to be null. That just signifies a privileged window/document that only
can be listened to with privileges.
I added GetPrincipal/SetPrincipal methods to nsIEventListenerManager.
nsDocument::GetNewListenerManager sets a principal on the listener
manager when it creates one. Obviously there are other places that
create listener managers, but scripts seem to go through this one.
Another change is to save some memory usage. Currently I allocate an
array of PolicyType that is NS_DOM_PROP_MAX elements long.
Unfortunately, compilers appear to allocate four bytes for each
PolicyType, so the array takes around 2400 bytes. I've added changes
to use two bit vectors that should consume about 1/16 that space.

There are also changes that push nsnull onto the JSContext stack when
entering a nested event loop.

and efficiency.
Tighten checks on document properties and node properties. Should resolve
several bugs:
18965 document.firstChild vulnerability
19043 document.childNodes vulnerability
19044 document.lastChild vulnerability

Error if an interface is declared [scriptable], but contains methods that can't be scripted because they refer to native-declared types, unless the method is declared [noscript].
This change is intended to make it easier to determine when an interface is not scriptable, and to make it easier to see what changes need to be made to make it scriptable.
As many of the .idl files in the tree defined [scriptable] interfaces that contained non-scriptable methods, I've sprinkled [noscript] throughout. As the interfaces weren't scriptable anyway, this shouldn't change their visibility to javascript.
