This has been approached before here, but nothing came of it. These files
are encrypted with NSS found in the Mozilla Dev kit and in FF source.
I've been compiling information that pertains to this very task, but with focus
on FF as opposed to TB.
The previous thread about FF/signons.sqlite:

Firemaster does provide source:

Some additional code I've found:

"global salt" is important (naturally)
I've created a number of example files I'll post a link to in the morning.
Again I'm no programmer but I did a bit of research the last few weeks
into this issue and those are basically my notes :)
