I think there should be maybe a howto or conversion utility or something to help people convert firefox XPIs to k-meleon plugins or whatnot. that would be a more sensable plan and would open up a lot of options
It is not that easy to convert Firefox extensions
to K-Meleon as they are.
K-Meleon has a different browser structure.
Some Firefox extensions may work after being worked on,
for others it is not possible to make them work,
or it is possible only after a complete reconstruction
of the extension.
