Firefox 3 is in my Eee PC. Finally, someone made it easier (relatively) to install it. Mind you, it still needed a bit of tweaking via the EeeUser forum. The key addition being
sudo dpkg -i --force-conflicts libgtk2.0-0_2.10.11-1_i386.debA sort of "force install", then a visit to synaptic (sudo synaptic) to resolve some problems (fix broken packages).
