Bug 1451159 - [testing/profiles] Store profile data in actual profile look alike folders r=gbrown This moves testing/profiles/prefs_general.js to testing/profiles/common/user.js. It also adds an 'extensions' folder to the common profile. Dropping extension files here will get them installed in all test harnesses (useful for testing on try). The idea is that all test harnesses will eventually use this 'common' profile. We'll also create some new per harness profiles, e.g testing/profiles/mochitest and testing/profiles/reftest. This way there will be a single location developers can go to set preferences, both for a specific harness, and across all harnesses. MozReview-Commit-ID: 8sqBqLiypgU
