Bug#911364: firefox-esr: Master password lost after update from ESR v52.9.0 to ESR v60.2.2 (along with all user certificates and saved passwords)

[Bernie Elbourn]

I have a terminal served system but I am unsure who might have the issue.

Is there a way to scan the users firefox settings to see how many users have the 
"master password" set?

Huge thanks,

Bernie
