I have the
firefox package (Firefox 3.6) installed in Ubuntu 10.04. I'd like to install Firefox 4.0 from the Mozilla PPA but keep 3.6? The instructions look like they'll replace the current firefox package with the new firefox. Is it possible to install both using apt-get? Is there a way to name the executables
firefox-4.0 and have
firefox point at one of them?
If you can't use apt, what's the best way to install multiple packages with the same name that will automatically update themselves (or at least be easy to update)?
