I used a long master password and tried to hack my own vault using one of the free software I found online, and somehow it didn't work. But I see some blog posts saying that it's possible to crack the vault even if it is protected by master password with some sophisticated software. I don't know if this is true or not. Didn't try this out yet. 

So I want to use Firefox password manager because I don't want to pay for paid password managers and because I'm broke. Norton identity safe is not very responsive and I can't use that with firefox anymore. I got to know about firefox password manager and I used a master password. But I found out there are so many free hacking tools available to crack firefox password vault. https://www.raymond.cc/blog/how-to-find-hidden-passwords-in-firefox/ I used a long master password and tried to hack my own vault using one of the free software I found online, and somehow it didn't work.

Didn't try this out yet. http://realinfosec.com/?p=132 Why doesn't firefox use AES 256 encryption which is the fastest and safest encryption technology like other password managers like Norton identity safe and lastpass and dashlane? Why does it use 3EDS protection which is quite old, slow and not as safe? I don't have time to test if firefox vault is really crackable with free hacking tools. How can I know my passwords are safe? I use norton identity safe for now, but copying and pasting from norton vault is a pain. Thanks for your opinion.
