Firefox 144 now uses AES-256-CBC instead of 3DES-CBC #120
Description
As of sometime around Oct 1, 2025, Firefox now uses a different encryption algorithm, so firefox_decrypt.py no longer works.
To reproduce, just attempt to run against a version of Firefox >= 144. I get:
ERROR - Username/Password decryption failed. Credentials damaged or cert/key file mismatch.
Linux Mint 21.3 (Virginia) 64 bits
Firefox 144.0.2
Python 3.10.12
firefox_decrypt.py 1.1.1+git
