I installed lucid's linux-image 2.6.32 and firefox 3.6 on a jaunty box
with the following. You can adapt this to your case but be warned that
I was just messing around so did not care whether I broke anything.
All is well though up to now.

o edit /etc/apt/sources.list to add lucid (if you choose jaunty or
karmic, you will also have to add jaunty-updates or karmic-updates)

o edit /etc/apt/preferences always to prefer jaunty to lucid (if you
choose jaunty or karmic, you will also have to add jaunty-updates and
jaunty-security or karmic-updates and karmic-security):

Package: *
Pin: release a=lucid
Pin-Priority: -10

Package: *

Pin-Priority: 900

Package: *
Pin: release a=jaunty-updates
Pin-Priority: 900

Package: *
Pin: release a=jaunty-security
Pin-Priority: 900

o run

o run
aptitude purge ubufox firefox firefox-branding firefox-3.0
