FireMasterLinux is the Linux port of popular FireMaster tool, an initiative by the elite members of  “rainbowsandpwnies” security group.  The team is headed byBroseidon along with fellow members. Currently base version of project is ready for Linux with the support for brute force password recovery.

FireMaster is the first ever built tool to recover the lost master password of Firefox. In order to protect the stored login passwords, Firefox uses master password. If the master password is forgotten, then there is no way to recover the master password and user will lose all the stored login passwords as well.

In this direction, FireMaster helps in recovering lost master password to get back all the stored passwords. FireMaster uses combination of techniques such as dictionary, hybrid and brute force to recover the master password from the Firefox key database file.

Often it takes long hours and some times days together to completely recover the master password based on its length and complexity. Hence one end up performing recovery operation for days continuously. However Windows system often goes slower as the day passes and performance is not optimal when it comes to continuous processing.

In such a case where it involves processing for long hours with consistent high-performance, Linux becomes the ideal platform. To address this exact problem, we have started the project, FireMasterLinux….!

Currently project is under development and progress of the same will be updated on the official project page . If you would like to join hands in this project, please drop him a line at, or join the discussion on the forums at

Update: Released FireMasterLinux 0.2 version with various command line options including -m & -c for char set specification. Check it out
