    this is great but won’t this leave version 2.x still on my machine.

    should I uninstall 2.x first or second?

    Reason I ask is i want as many of my add-ons to migrate over as possible.

    Thanks for the information though – it just shows how easy ubuntu is.

    followed these instructions and still stuck with ff2, do i need to change the launcher icons somehow? how do i know if it actually installed?

    What do you see when you go to Help > About?

    The the launcher icons definitely fire up ff2. I found granparadiso installed in Synaptic Package Manager and removed it – I didn’t realise this was an alpha version of ff3 until I had done some reading up.

    Now if I enter the terminal commands you’ve provided, granparadiso reappears. I assume I have to update or get rid of the packages somehow?
