recently i reinstalled
i went to synaptic searched firefox-3.5 and installed it.
so on menu it seems as shiretoko.when i place the over it ,says firefox 3.5 beta.
what will i have to do to get firefox 3.5(the stable one) without messing up with the ppa.launchpad....(because i did that and it just didnt work) and have the updates?

if i dont have any other choice please give me a guide on how to install through the official webside(and have later updates )?
