When I start Firefox, the password manager window asking for master password pops up in a few seconds even when I have not gone to any specific website that requires me to login. I have the Zotero addon installed which requires login to synchronize itself. However, when I am not visiting a website and the password manager's master password window pops up, I am not sure of what application/website is requiring a password. Is there a way for me (as a user) to know what application is trying to obtaining a login/password from Firefox's password manager?
