Most +specifically, unregister() calls need to propagate across all +content processes. There are fixes on bug 1318142, but they're +ugly and complicate things. + +Specific test notes and rationalizations: +- multi-e10s-update: This test relies on there being no registrations + existing at its start. The preceding test that induces the breakage + (`browser_force_refresh.js`) was made to clean itself up, but the + unregister() race issue is not easily/cleanly hacked around and this + test will itself become moot when the multi-e10s changes land. |
