Details

Seen this in several Firefox UI tests which test the session restore feature and restart Firefox a couple of times. Right after requesting a shutdown, the following Javascript failure is visible: https://treeherder.mozilla.org/logviewer.html#?job_id=172680367&repo=autoland&lineNumber=50964 > 14:42:37 INFO - JavaScript error: resource:///modules/AsyncTabSwitcher.jsm, line 248: TypeError: browser.frameLoader is null
On MacOS we actually get an additional assertion, but not sure if that is related to the filed bug here: https://treeherder.mozilla.org/logviewer.html#?job_id=172675101&repo=autoland&lineNumber=43314-43340 > 07:05:26 INFO - Assertion failure > 07:05:26 INFO - assert@resource:///modules/AsyncTabSwitcher.jsm:447:36 > 07:05:26 INFO - postActions@resource:///modules/AsyncTabSwitcher.jsm:542:5 > 07:05:26 INFO - onUnloadTimeout@resource:///modules/AsyncTabSwitcher.jsm:623:5 > 07:05:26 INFO - unloadNonRequiredTabs/this.unloadTimer<@resource:///modules/AsyncTabSwitcher.jsm:655:46
