The patch I'm about to attach makes all of the tests under extensions/test/browser pass locally for me with a windows 7 debug build except for bug 584944 (see bug 584944 comment #47 for details as to why I think that test is still failing).

List of tests that failed on me without the patch. I am quite certain that several of these tests failed due to previous tests failing. browser/browser_bug581076.js browser/browser_details.js browser/browser_discovery.js browser/browser_install.js browser/browser_list.js browser/browser_searching.js browser/browser_updatessl.js browser/browser_uninstalling.js browser-window/browser_bug562890.js browser-window/browser_bug581076.js browser-window/browser_bug591465.js browser-window/browser_bug596336.js browser-window/browser_details.js browser-window/browser_globalwarnings.js browser-window/browser_install.js browser-window/browser_list.js browser-window/browser_searching.js browser-window/browser_uninstalling.js

With this patch the only tests that fail (including the xpinstall tests) on my system are browser/browser_uninstalling.js browser-window/browser_uninstalling.js per comment #1 and bug 584944 comment #47 it appears there is more to do for browser_uninstalling.js Better still is that the only errors for these tests are TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_uninstalling.js | Test timed out TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_uninstalling.js | Found a tab after previous test timed out: about:addons TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser-window/browser_uninstalling.js | Test timed out TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser-window/browser_uninstalling.js | Found unexpected add-ons manager window still open I'm used to getting an extremely long list of failures.

btw: there were a couple of tests that needed the requestLongerTimeout in close_manager for them not to time out. Also, I don't have a preference regarding making the value for the call to requestLongerTimeout a parameter for open_manager / close_manager and am fine with removing it if you prefer.

Couple of notes: Bug 607821 mentions the timeout in browser_bug581076.js though it isn't obvious that it isn't due to the previous timeout in browser_bug557956.js... it is a separate timeout. Bug 604136 (browser_bug562890.js) will likely be fixed by this Looks like increasing the timeout for browser_bug562890.js in bug 604136 fixed it for the tinderbox but it didn't fix it for me. Bug 607821 (browser_bug557956.js) will likely be fixed by this Bug 579540 (browser_bug553455.js) might be fixed by this Bug 603557 (lots of intermittent failures) might be fixed by this Looks like increasing the timeout for browser_searching.js in bug 585212 fixed it for the tinderbox but it didn't fix it for me. Looks like increasing the timeout for browser_details.js in bug 593622 fixed it for the tinderbox but it didn't fix it for me.
