window.setTimeout is not working properly for long delays #1549

I've been having a problem with window.setTimeout. It only seems to work for low timeout values (up to about 4 seconds). With a longer delay, the callback function is never run.

For example, try this script:

// ==UserScript==
// @name Timeout test
// @include *
// ==/UserScript==

window.setTimeout (function() {alert ("At timeout");}, 2000);

The alert fires as expected after 2 seconds. But when I change 2000 to 5000, the alert never happens.

Using Firefox 12 and GM 0.9.19.


Confirmed working OK on 0.9.18.


Most of my scripts stopped working this morning after auto updating greasemonkey to 0.9.19 due to this same problem.
I recommended my users to disable auto updating and downgrade to 0.9.18
