Hi, In order to reduce the performance issues caused by sync IPC messages, we are tracking and removing sync IPCs from the content process or the UI thread[1]. With bug 1336919 landed[[2] all additions of new sync messages must be recorded in ipc/ipdl/sync-messages.ini and reviewed by an IPC peer. Shortly we will also extend the WebIDL hook to block unreviewed changes from pushing[3]. This is to ensure that we don't add sync IPC messages that cause performance issues needlessly. We appreciate your understanding.
