If I launch Firefox 49.0.2 and then unlock my vault to enable autofill, that works ok.
If I then close down Firefox and then launch it again, I have to unlock my vault again in order to enable autofill.
Why is this? In both Chrome and IE, once I have opened my vault I can then close and relaunch the browsers as many times as I like and the vault always remains open.
It's a pain having to keep reopening my vault every time I relaunch Firefox.
Does anyone have a way round this?
