usually this browser is totally reliable, but today? keeps going out of sync, I must have re entered my details to sync 20 times today, and it is still doing it. I use firefox because it is secure and has reliable features, but at this point I can no longer use personas (and nobody has helped me with this yet), and now a syncing problem that persists. If the best features of this browser are no longer available (like syncing and personas) could you please... 1/ help me resolve this issue or 2/ recommend a browser that works reliably Thank you
