For those who don't read Gen X's spanish (I don't either) I think from the links that he's advocating the adobe 64bit flash beta. I've been running it for over a month now (no npviewer.bin issues any more, plus flash runs faster and controls in youtube &c. work more consistently.) To try it uninstall the current flash plugin with synaptic, then go to the download page (first link in GenX's comment) and download 64bit flash for linux. Then copy the plugin file to one of the mozilla plugin directories (~/.mozilla/plugins for just you or /usr/lib/mozilla/plugins for systemwide). Restart firefox. Done.
