Hi Martin, As Victor noted the snippet you provided is JavaScript. Anyway, being a new Linux enthusiast, I checked the site you mentioned with FireBird and there was no sound. I followed the plugin link to netscape which then lead to another site which has a useful page for testing plugins: http://fredrik.hubbe.net/plugger/test.html I'm running 9.0 and upon searching the distro cd's I found and installed: Plugger which actually installs mozplugger into: /usr/lib/browser-plugins I then had to copy mozplugger.so into /opt/MozillaFirebird/plugins At this stage I wasn't entirely sure if it was working as I then tested the Audio/Midi link on the above mentioned to no avail and ended up also installing Timidity and Playmidi (also on the distro's) Frustrated I then clicked on the Audio/MP3 link on the test page and got some sound so I then checked back at the www.all-yours.net site and hey presto! I got to hear some jingle bells. A quick google leads to: http://mozplugger.mozdev.org/ as a place to find the mozplugger rpm. If all else fails I could send you mozplugger.so etc It would be nice if one could update FireBird with paths to other likely plugin directories. HTH.
