Dunno if this helps you at all, but I’ve been using BitWarden to manage my passwords since I made the switch from Chrome to Firefox (both on PC and my Android phone). It doesn’t fill passwords automatically in either case, but it’s not much extra work to invoke BitWarden to fill those fields as-needed on either device, and it works very consistently. It’s also (I’m told) much more secure. Just thought I’d share that here!
