ragingcheetah distro are you using . the new ff should be in YOUR distro software repo ( yum , apt-get,synaptic,...)

from the install instructions ( all quotes are copied from the instructions)
to repost that page
http://support.mozilla.com/en-US/kb/...refox+on+Linux
there is NO INSTALLER it is a binary download
you DID NOT PUT it in the root home folder you put it in YOUR user home folder
also DO NOT RUN FIREFOX AS ROOT - that is a very bad idea .

WHERE did you save the tar.bz2 ( it should be in your user home folder )
1) extract the file to your home folder
"~" is your user home folder
2 ) 3)
run the firefox binary file
also WHAT distro are you using

thanks John.....
i really admire your patience while explaining the basics to me...
now i know the meaning of "~" in linux.....
i am not really sure of the word "DISTRO".....
i think you are talking about the flavour of linux.....if i am correct then it is pardus 2008...
thanks once again John..... firefox is working fine....!!!

Some packages can't be installed with configure. I am also having this problem. The messages i receive after typing the command ./ configure . I am receiving the following message : bash: ./configure: No such file or directory.

Of course bash is shell command : "shell programming" means writing code that is a command shell executes.

Shell is a user program or it's environment provided for user interaction. Shell is an command language interpreter that executes commands read from the standard input device (keyboard) or from a file.
In early days of computing, instruction are provided using binary language, which is difficult for all of us, to read and write. So in Os there is special program called Shell. Shell accepts your instruction or commands in English (mostly) and if its a valid command, it is pass to kernel.

Now you know how it works.
I have noticed that you have firefox/run-mozilla.sh file. This file is executable with the following command : sudo sh firefox/run-mozilla.sh

It works fine with me
