ob211,
thanks for your help, but this is what i got, what do you make of it?

misha at misha-desktop:~$ sudo apt-get install firefox
Reading package lists... Done
Building dependency tree... Done
Package firefox is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libnss3
E: Package firefox has no installation candidate

thanks again, all the best, over and out!!

ciao,
misha
