Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.
1 // Basic preventExtensions test.
3 var g = newGlobal();
4 var obj = g.eval("({x: 1})");
5 assertEq(g.Object.isExtensible(obj), true);
7 var dbg = new Debugger;
8 var gw = dbg.addDebuggee(g);
9 var objw = gw.makeDebuggeeValue(obj);
10 assertEq(objw.isExtensible(), true);
12 assertEq(objw.preventExtensions(), undefined);
13 assertEq(g.Object.isExtensible(obj), false);
14 assertEq(objw.isExtensible(), false);
16 // Calling preventExtensions again has no effect.
17 assertEq(objw.preventExtensions(), undefined);
