been trying to upgrade seamonkey from 2.48 to 2.49.2.
I tried this:
downloaded seamonkey to my home directory.
Open a Terminal and to home directory:
cd ~
Extracted the contents of the downloaded file:
tar xjf seamonkey-*.tar.bz2
started seamonkey
~/seamonkey/seamonkey
this worked though with error messages.
I dont know how to create an icon in applications/internet for version 2.49.2
