Package firefox is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'firefox' has no installation candidate

i always get this when installing firefox. is there a way?
so with flash.

firefox is forked in Debian, and its name is iceweasel.
Do:
apt-get install iceweasel
If you want to know when and how and why... do a short search on the WWW.

For flash you need contrib and or non-free in your /etc/apt/sources list. For example:

deb http://ftp.de.debian.org/debian/ squeeze main contrib non-free
