firefox 3 rc3 install

[Mike Adolf]

Greetings,

I am having problems with Firefox as bundled with Ubuntu 8.04.  To fix I 
downloaded rc3, but can't figure how to install it.  I had expected a 
configure.sh file, but their is none.  After un-taring, the directory 
contains all the .so files and firefox binary.  I can run it locally 
from the directory.  When I did, it ask me to accept the license. I 
would like to have it installed in /usr and all the .so in the right 
place.  I would be great if apt-get could also recognize that it is 
installed. Maybe I need to build my own .deb file--I hope not! Any 
ideas?  BTW, rc3 seems to fix the downloading problems I was having with 
Ubuntu version.

Thanks, Mike
