I've been planning on removing as much test specific code from the client binaries which is much simpler now that there is a test updater and tests that are already covered by other tests. The MOZ_NO_REPLACE_FALLBACK env var isn't needed and the tests that use this env var are for the most part already covered by other tests and with a few changes these tests can completely cover those tests. Patch coming up soon.

Comment on attachment 8611071 [details] [diff] [review] patch rev1 Removes 14 Windows only tests! :)

Note regarding the try run. I used --tag appupdate which causes the mochitest-other tests to report failure on treeherder due to there being multiple test suites and treeherder reporting failures if any of the test suites don't run any tests (see bug 1162355). I've looked at the logs and verified that all of the mochitest-other tests passed.

The Windows builds systems suffered an automation error so here is a Windows only try push https://treeherder.mozilla.org/#/jobs?repo=try&revision=ca2e72b8cc66

Yay again... this removes two tests that have been intermittent! Bug 1112284 and bug 1166989
