Hai,
I installed vlc portable 2.0 and firefox portable 3.6 on my usb drive. After installation I copied libvlccore.dll, npvlc.dll, libvlc.dll from vlc portable installation to the plugins directory of the firefox portable. Finally, when I tried to open the webpage containing an mp4 video, the firefox is not playing the video. But when I checked the plugins installed on the firefox, it shows that the vlc-webplugin is installed. Is the vlc plugin portable ?.
