And a lot more than I can fit in here.
the timing out part of the test has been added in bug 959531, tht I can't access atm, moreover from when this has been done we should also split this test into 2 parts to avoid bug 916405.

Btw, looks like waitForLoad never calls back, though the page clearly loaded since on test close we find it.
Note that waitForLoad is a dupe, the test already has promiseTabLoadEvent that should basically do the same, so we should also remove that dupe helper
this should block bug 959531, though I can't make that change.
I cc'ed you on the bug, Marco. As far as I can tell, the problem happens here:

13:25:07     INFO -  TEST-KNOWN-FAIL | chrome://mochitests/content/browser/browser/base/content/test/general/browser_aboutHome.js | uncaught exception: AbortError at chrome://browser/content/abouthome/aboutHome.js:273

It looks like we're getting some sort of database abort while storing some snippets data?

the aborts are expected, when you close the tab there might be an indexedDB transaction ongoing and it gets aborted, I don't think they are related to the timeout, off-hand.

Depends on: 967014
Comment 9 and comment 41 are actual browser_aboutHome.js bugs, because the horrible hack of doing a search and hitting stop doesn't always work; everything else here is actually a releng bug, because the ancient Fedora slaves no longer run ntp, so their clocks eventually wind up set to 2001 when the example.com cert wasn't yet valid.
