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?
