Wow! Hello Pondus thanks for the list.... very useful
polonus, I used that extension, but I no longer use firefox ..... :'(
however I'm not looking for something like that, I'm looking for video capturing software.
Meantime another friend has suggested debut, seems it's supports more formats than CamStudio, and I think it's more user-friendly, it doesn't capture layered/translucent windows though, just tried to capture avast window with it.....and it's ended with invisible avast!
thanks
