Look at the Forums for most of that.
For more help,if not found at the Forums, join the IRC channel. With SeaMonkey it is easy.

You did not say which kernel or distro or release it is, I guess it is 6.10Dapper,Edgy or 7.04 Feisty.
Also Gnome or KDE. it makes a little difference.
After you run Synaptic and download.install make , reboot.
It works okay, make a backup, that is any OS, Linux makes it easy.
Have Fun!
