Re counters - build in XSLT, test in Moz (since it supports XSLT native),
and transform to HTML! It works on anything and makes better sense at the
present time.

In the main I find Mozilla easier to work with than Opera and better, I find
the Mozilla community is more helpful!
For example, this thread (group.google.com):
..stuff just doesn't work in Opera, and sometimes its just really really
hard to get the answers you need -- the news groups are fairly quiet so it
takes days to get a reply and often there's no work around, and the funny
part is that when there's a flaw, people don't seem to want to tell you
straight!  (sorry - just needed to vent a little!)

Not that I'm dis'ing Opera -- I do think it is a very good product, but for
me, I much prefer Mozilla.
