Review for Master Password+ by MakisH
Rated 5 out of 5 stars
This functionality should be included in Firefox by default. Although I want to use a master password to have better control on my passwords, Firefox keeps asking me for my master password in quite random times. I used this add-on mainly to suppress the master password prompts and choose when I want to see them.
It works in Firefox 50 with Multiprocess Windows ("e10s") enabled.
