there is no need to do anything. firefox comes as pre-compiles binary. type firefox and FireFox will pop-up. create symlink of firefox file in Menu OR on Desktop.

if I type firefox, it says u can install it from sudo apt-get....
and there are many things there and I cant figure out which one is the firefox installation

anyway, I did this
user@adminPC:~/FireFox/firefox$ ./firefox
./firefox-bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
user@adminPC:~/FireFox/firefox$

what should I do?

You need to install libstdc++:

# apt-get install libstdc++5

ok... but what is libstdc++?

[nalg0rath]

I believe it is a runtime library for C++ programs compiled with GCC (g++).

Read:
Standard C++ Library v3 - GNU Project - Free Software Foundation (FSF)
or google it.

i would suggest you to install firefox through apt-get or Adept only. it will install all dependencies and create symlinks automatically.

sudo apt-get install firefox
