I just tried to install videochat plugin in gmail but when i restart the browser it seems like the plugin is not installed. It looks exactly the same way as before the installation.

[insult removed.]

Same here, since I don't use it I don't care about it. I tried several times though

BTW i have Windows Vista, FF 3.5beta4 (but it didnt work even on beta 3), Chrome 2, Opera 9.64, IE8 and i doesnt work on any of these.

And sorry for the insult. My shoolmates were joking ;)
