With the changes performed in
https://github.com/greasemonkey/greasemonkey/issues/issue/1258
, a bug arises.
The change performed can crash scripts worked before 0.91. In version
0.90 and before, the window variable was shared between scripts. The
following example works:
// ==UserScript==
// @name Script1
// @namespace http://test.free.fr
// @description Script1
// @include *
// ==/UserScript==
window.a=1;
-
// ==UserScript==
// @name Script2
// @namespace http://test.free.fr
// @description Script2
// @include *
// ==/UserScript==
alert(a);
And with this change, the second script crashes.
A workaround trying to solve the bug and maintaining the backward
compatibility is:
var unsafeContentWin = wrappedContentWin.wrappedJSObject;
+ var safeContentWin = new XPCNativeWrapper(unsafeContentWin);
// detect and grab reference to firebug console and context, if it
exists
var firebugConsole = this.getFirebugConsole(unsafeContentWin,
chromeWin);
for (var i = 0; script = scripts[i]; i++) {
...
// Re-wrap the window before assigning it to the
sandbox.__proto__
// This is a workaround for a bug in which the Security Manager
// vetoes the use of eval.
- sandbox.__proto__ = new XPCNativeWrapper(unsafeContentWin);
+ sandbox.__proto__ = safeContentWin;
