Hi carlos,
Yes - Roboform works. & it would work better if they decided not to boycot K-Meleon
& put our exe into their supported browser list
As it is You will find a workaround at:
K-Meleon's Extension Page. Additioally You need to install a fairly new Roboform Main Program. I use Version 6.9.8. The free version is sufficient for most things.
The only disadvantage: the workaround uses up the the start with homepage function.
