Same LSAN leaks as other suites, albeit intermittent. Beyond that, bug 1273887 and bug 1123438 hit at a very high frequency on opt: https://treeherder.mozilla.org/logviewer.html#?job_id=31673601&repo=try https://treeherder.mozilla.org/logviewer.html#?job_id=31673275&repo=try On debug, various webext tests are basically permafail. https://treeherder.mozilla.org/logviewer.html#?job_id=31674227&repo=try https://treeherder.mozilla.org/logviewer.html#?job_id=31674035&repo=try Also on debug, bug 1285701 is permafailing: https://treeherder.mozilla.org/logviewer.html#?job_id=31674042&repo=try And a frequent e10s-only toolkit/modules/tests/browser leak: https://treeherder.mozilla.org/logviewer.html#?job_id=31674024&repo=try Lots of other random timeouts on debug, hard to say how much 16.04 is at fault specifically, though. The one in browser/base/content/test/tabcrashed/browser_shown.js seems particularly prevalent, though. Also, the sessionstore tests are quite timeout-prone too. Finally, bug 1306666 is permafailing on debug. https://treeherder.mozilla.org/logviewer.html#?job_id=31674511&repo=try https://treeherder.mozilla.org/logviewer.html#?job_id=31674500&repo=try
