In bug 1697195, we tried to auto-enable SW-WR with Fission is enabled. Unfortunately, some tests failed when run with Fission + SW-WR mode: Marionette failures: https://treeherder.mozilla.org/jobs?repo=autoland&searchStr=linux%2C18.04%2Cx64%2Copt%2Ctest-linux1804-64%2Fopt-marionette-headless-fis-e10s%2Cmnh-fis&tochange=a24d9f6247aa4211e227c56db389df0255fc7cc7&fromchange=03e3558727b689d50eefeb19f0d927341d8f2255&selectedTaskRun=M9DmAYu0RHeQ11LnVoLMsw.0). https://treeherder.mozilla.org/logviewer?job_id=332576581&repo=autoland&lineNumber=57773 `TEST-UNEXPECTED-FAIL | testing/marionette/harness/marionette_harness/tests/unit/test_reftest.py TestReftest.test_cache_multiple_sizes | AssertionError: 'FAIL' != 'PASS'` Note that this test is expecting test result "FAIL", so this "TEST-UNEXPECTED-FAIL" result means the test returned "PASS" with Fission + SW-WR! I don't know if this test failure requires Fission + SW-WR or just SW-WR. This bug may be caused by or fixed by Puppeteer bug 1693011.
