[ubuntu-users] Ubuntu 9.04 and Firefox browser

[Ted Hilts]

I was doing some work with SUN Virtual Box and used Ubuntu 9.04 as a 
GUEST along with several other Linux Guests. It seemed to me that there 
were few if any Add-Ons for Firefox one example being the Scrapbook 
add-on.  This worried me and then I realized that my present Ubuntu 
upgrade is 8.04 up from 7.10 and I have received no automatic upgrade 
yet to 9.04. Is 9.04 considered a stable release and if so why would my 
Ubuntu 8.04 not be automatically upgraded? And where are the add-ons if 
9.04 is ready to be upgraded?

Puzzled!
