ERROR - Passwords protected by a Master Password! It's not about firefox_decrypt

[unode]

Hi @doa379 , I'm using the same browser, version and also using a profile without password and cannot reproduce the problem.

Try running: firefox_decrypt.py -vvv for extra debugging information.

Hello,
having exact same issue:

$ ./run_all Passed: 33 Failed: 0 Unexpected successes: 0 Skipped: 0 Expected failures: 0 Runtime: 1.73 seconds

Please find output of -vvv flag:

Hi @iketanijus,

From the log it's using libnss in the system library path. Do you by any chance have libnss installed through your system's package manager?

Yes, I am using Slackware64-14.2 Linux. It has libnss3.so library provided by mozilla-nss-3.40.1-x86_64 package by default.

@iketanijus unless I'm misunderstanding. On the log, you didn't provide a master password but the username later on is still encrypted.

The tests above also passed so there is either a problem with your password input or your profile.

Yes, I did not provide any password (just hit enter key on prompt), because that profile does not have any master password set actually. If I start Firefox from that profile, then I can see all the saved passwords without entering any master password. Still script complains that it's set for some reason, while it is certainly not.

I'm using nss-3.46.1 here and everything works as expected. In the past we had users reporting problems when using libnss installed with the system's package manager. I've managed to reproduce it on Fedora but if compiled manually it worked fine so it was some kind of packaging incompatibility. In this case tests pass, so it seems like it's a different problem.

A few steps you can try to troubleshoot this:

1. chdir into the folder where firefox/thunderbird is installed. Check that libnss.so is present and run firefox_decrypt from that location.
2. Create a new empty profile and add save a password without adding a master password. Check if the same problem appears.
3. Download NSS from here, compile manually and try running the script with this libnss.so.

If all still fail, could you share the profile you created in 2 so I can try to reproduce it on my side?

This should be fixed in the latest version.
