Comment 48 for bug 443121

I have seen something that could be interesting, maybe you already know:
Opening ~/.local/share/desktop-couch/couchdb.html you could see a manager of the couchdb, the problem seems to be that FF records a lot of versions for each bookmark (maybe each time you access) and can be solved using "Compact", deleting all old versions and "deleted" bookmarks, now it's 0.8MB.
This is only a temporal solution.

But you can also configure the max size of the database (in "configuration", at the right), for me (Lucid 64, FF 3.6 updated) it's by default at 4GB, the same size I have read here. I change it to 10MB and I will report if it works.
It's the max_document_size, there is another one, max_attachment_chunk_size, that I don't really know what is it, but it was also at 4GB and I changed it to 10MB too.

Maybe if you psypher haven't delete it (or even if you do, maybe) can check the size for you.
