Feature Status Review
- Firefox 87 is GREEN as most features have been confirmed with owners as ready to ride the trains
- Waiting to get some clarity around (op Sites - move to Remote Settings). I think we're OK here but the transfer of EPM ownership is causing some delays in reporting.
- Firefox 88 is GREEN as feature list is light and ready for merge across the board
- Facing some similiar issues getting updates from Search as mentioned above.
