Our UX team helped us decide to turn on tabs-on-demand + do tab restore by default, Bug 711193. This change will make interacting with the browser more responsive after startup, help MemShink and not trigger as much captive wifi portal badness.

Frontend people are busy adding telemetry to everything that matters, bug 671038. Some of this has already paid off in terms of us catching a tab animation regression in bug 724349. We plan to switch our awesomebar searching from SQL to an FTS. If you are a text-search/tokenizer expert, perhaps you help us with bug 725821. There is also a lot of activity on making various sync IO things async, see the meeting notes for complete details.
