By popular demand (that is myself plus one) an updated bookmark
conversion from firefox to elinks and back again. I haven't tested it
with firefox because it is broken at the moment, but it appears the
same when I open it in elinks.

It is very basic, it doesn't have a lot of the stuff that are hidden
in the angle brackets with last access, date etc, but it will probably
do the job for what is needed!
