See the URI list attached in bug 658738 -- lots of http://example.com/browser/toolkit/mozapps/extensions/test/xpinstall/* in there. The amount of windows leaked makes me think that some central piece in the test framework or in the actual code must be responsible for this.

by test framework I mean toolkit/mozapps/extensions/test/browser/head.js

Err, more likely toolkit/mozapps/extensions/test/xpinstall/head.js

Perhaps related to bug 669240?

Bug 695480 made these leaks disappear.

(In reply to Serge Gautherie (:sgautherie) from comment #7) Oh, leaks are fixed, but code has a "remaining" issue: { TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/xpinstall/browser_navigateaway2.js | Console message: [JavaScript Error: "can't access dead object" {file: "resource:///components/amWebInstallListener.js" line: 176}] } Code is http://mxr.mozilla.org/mozilla-central/source/toolkit/mozapps/extensions/amWebInstallListener.js#175 117 Installer.prototype = { ... 126 checkAllDownloaded: function() { ... 176 if (failed.length > 0) { PS: SeaMonkey didn't port this test (yet).

We're clearly not going to do anything else in this bug. If there are still issues file a followup please.
