Fingerprint and location tweaks

[Imnotndesh]

Changes made

1. Realised you were only checking for the first fingerprint enrolled and added check for all enrolled fingerprints
2. Added logic to create ~/.mozilla folder. This is due to firefox 147+ introducing storing to the default XDG directories inside of ~/.config/mozilla. I initially added logic to install the native-messaging-hosts inside the same dir but also realised a currently open bug being tracked by firefox under here where the directories are yet to be used by firefox for the current extension purposes. So i defaulted to install to both old and new locations since the fix might be tracked to stable.
3. Added firefox flatpak directory too since it was not handled in the installer
