That's nice to know :)

Where does it store it? Does it ask the user for a location? I know on 
some machines I admin there is no writeable space for the user on the 
local machine. Well except from /tmp but it gets wiped on every boot....

Obviously the best solution all round is if sqlite worked over NFS. With 
FF3 using it for some stuff it's another nail in the "Using NFS" coffin :(
