libnss not found (libnss3.so)

Hey @onehdev

I took the 9kwbffy3.default/ Firefox profile from my MacBook v10.13 using Firefox v60.0.2 and saved it to my Kali machine.

Using the below command in Kali:

> python3 dumpzilla.py /path/to/9kwbffy3.default/

[ERROR] Error decoding passwords: libnss not found (libnss3.so)
[WARNING] No session info found!

I've installed python-nss using pip3, libnss3* and nss-passwords using apt-get but still dumpzilla gives the same error and isn't able to decode the passwords. After trying older versions of dumpzilla, this issue doesn't exist. I think it started with this commit but I'm not positive.

Any help here would be great. I'm hoping to feature dumpzilla in one of my articles this week.

Hi @tokyoneon ,

Could you tell us which are the libnss locations in your computer?

Thanks!

I don't know if this a good way in solving this problem. But I solved it changing the path in the script
from

elif sys.platform.endswith('win') == False: # LINUX`
        libnss_path = "libnss3.so"

to

elif sys.platform.endswith('win') == False: # LINUX
        libnss_path = "/usr/lib/x86_64-linux-gnu/libnss3.so"
