ie8, FF14 and the Remote Console

Hello Friends,

I'm trying to install Ubuntu in vmware server 2 and I experiment two curious behaviours :

within FF (14.0.1), the summary/console/tasks/events/permissions tabs do not show up (so no way to access the console to install the add-on)

within ie (8.0), the tabs are there, the "install plug-in screen" too, but installing the plug-in gives no result. I closed all ie instances, restarted ie, and when i wish to access the console, I still have the screen "please install the plug-in"

Thanks for your help
