Can I copy "libflashplayer.so" to "~/.mozilla/firefox/????????.default "?
the EXACT same way you would have on Microsoft windows
right click and select "copy"
navigate to the folder and right click and select "paste"
but on linpus light 1.3 you might be stuck with using what is installed flash8 and firefox2
linpuslight is the worst os there is
you are ,by far, better off installing linux mint lxde ( the light netbook version)
and removing linpus light from the computer
please do a lot ( or some ) research and install a new operating system
or live with what is already installed
