This is a meta bug to track the work needed to get the browser-chrome tests running in e10s mode. This bug tracks the work needed so failing tests can be disabled in a sane way such that all enabled tests pass - it does not track the work to make all such disabled tests pass. Later we will want more than the b-c tests, but the bulk of the work done here will benefit those other tests too. More context at https://groups.google.com/forum/#!topic/mozilla.tools/PL7yVc7rOnA
This meta bug is no longer used, bc tests are tracked directly in bug 984139.
