I like to keep my PC (and Firefox) logged in for weeks. When I start Firefox, it asks for my master password the first time I need a password I have saved. After that, it always automatically fills in each password.
Can I reset it so that it will go back to prompting me?
Not every time, just the first time after the reset.
This way I can re-lock my session overnight. I know I could simply shut down firefox and restart it but I don't want to do that as I often keep lots of windows open to remind me the next day what I was working on the night before.
