 - **AutoFirma** for digitally signing documents and authenticating on various Spanish administration websites—because ink and paper are so last century.  
 - **DNIeRemote** for using an NFC-based national ID via an Android device—no more digging through drawers for that card reader you haven’t seen since 2010.  
 - **Configurador FNMT-RCM** for securely requesting personal certificates from the Spanish Royal Mint—yes, the mint that makes actual coins.  
+- Integration with **Mozilla Firefox** (provided on both the NixOS and the Home Manager modules) that allows Firefox to communicate with AutoFirma, as required by some sites—now with automatic setup!
