Almost identical to gfxPrefs, with the exception that preferences can't be set (as it doesn't work with e10s anyway). The generated code size is tiny enough that we don't have to bother about having duplicates. MozReview-Commit-ID: 5SZyscvIzzS --HG-- extra : rebase_source : 1a2577bbe24d2d6644c3f1f5d0c47850b67fdea0
