as we work towards getting our tests running on task cluster (ubuntu 12.04 on amazon ec2, with docker as a container) there are many tests which are failing. We need to figure out why these tests are failing. [browser_private_search_perwindowpb.js] - this causes browser_searchbar_smallpanel_keyboard_navigation.js to fail with these errors: 618 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | There should be 3 suggestions - Got 0, expected 3 624 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #1 should be selected - Got null, expected [object XULElement] 625 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #2 should be selected - Got null, expected [object XULElement] 626 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #3 should be selected - Got null, expected [object XULElement] 627 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #4 should be selected - Got null, expected [object XULElement] 628 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #5 should be selected - Got null, expected [object XULElement] 629 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #6 should be selected - Got null, expected [object XULElement] 630 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #7 should be selected - Got null, expected [object XULElement] 631 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | the one-off button #8 should be selected - Got null, expected [object XULElement] 632 INFO TEST-UNEXPECTED-FAIL | browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js | Uncaught exception - at chrome://mochitests/content/browser/browser/components/search/test/browser_searchbar_smallpanel_keyboard_navigation.js:108 - TypeError: textbox.selectedButton is null ...

Here is a link to an inspect task from automation: https://tools.taskcluster.net/task-inspector/#Snq6nhcKRyGXhRIeXdx48g/0 Ideally we can figure out the root cause and fix this.

this might be specific to the lack of a window manager- will close this out when we test with a proper window manager on try. locally it seems to fix the problem.

The following push will clarify if this issue was related to the lack of Window manager or not: https://treeherder.mozilla.org/#/jobs?repo=try&revision=fbe188bab4b0

Many things have changed since this was filed. This was a bc7 job and it is running green these days.
