User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20160507231935 Steps to reproduce: Restart Firefox from the menu: File → Restart. Actual results: Firefox asks me for the master password for the SSD. Expected results: Firefox should have remembered the password.
I believe this is the expected behaviour as a new process is spawned. I'm not sure if there's a secure way to do what you propose.
I agree with Matt - there's no safe way to do this.
This is annoying because bug 1014979 was closed as WONTFIX, suggesting that a restart could be used as a workaround with no drawbacks. As possible solutions: * The two processes could communicate before the old one quits. * Or there could be a (user-side) PSM daemon. * Or use some other service on the machine (like Gnome Keyring - bug 309807?).
