Print (pdf) or Backup feature?

[Panabou]

I have preserved in Brief an RRS-feed that unfortunately is no longer online for many years, because the creator had unintentionally deleted his complete data. For me, this feed is still an irreplaceable scientific database, and I am very afraid that I lose the access in Brief in the future due to an incompatibility with future FF releases. I have already backed up the old Brief SQL database, but unfortunately I have not been able to get meaningful readable access to it. Ideally, there would be a print function (PDF) of a complete feed, which I miss a lot in Brief. Is there any possibility in this direction?
Thanks and best regards!
