I use and enjoy Firefox on my Ubuntu 10.04.2 laptop (although Firefox needs work for the Linux/Ubuntu version).
Yet I realize that in comparison to other pieces of software that have an "Ubuntu/Debian" version (
.deb file, and usually
.rpm files as well). I don't see it in one of the most profound assets of the FLOSS world.
The Question is - Why?
If Google Chrome/ium can , why can't they? It will be easier to get up-to-date software and features and so forth.
