About
Firefox Decrypt is a tool to extract passwords from profiles of Mozilla (Fire/Water)fox™, Thunderbird®, SeaMonkey® and derivates.
It can be used to recover passwords from a profile protected by a Master Password as long as the latter is known.
If a profile is not protected by a Master Password, passwords are displayed without prompt.
This tool does not try to crack or brute-force the Master Password in any way. If the Master Password is not known it will simply fail to recover any data.
It requires access to libnss3, included with most Mozilla products. The script is usually able to find a compatible library but may in some cases load an incorrect/incompatible version.
If you encounter this situation please file a bug report.
Alternatively, you can install libnss3 (Debian/Ubuntu) or nss (Arch/Gentoo/…). libnss3 is part
