Install flashplayer fails with Please enter the installation path

After downloading flashplayer from site http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash whenever I try to install flashplayer on my system it always ask me "Please enter the installation path of the Mozilla, Netscape,or Opera browser". It gave me a lots of pain.
1)Logon as a root user.
$su
Password:

2)Untar the file that you download from the site above.
#tar -xvf tar -xvf install_flash_player_9_linux.tar.gz

3)Run the installer.
debian:# ./flashplayer-installer

Adobe Flash Player 9 will be installed on this machine.
You are running the Adobe Flash Player installer as the "root" user.
Adobe Flash Player 9 will be installed system-wide.

NOTE: Please exit any browsers you may have running.
Press ENTER to continue...
Please enter the installation path of the Mozilla, Netscape,
or Opera browser (i.e., /usr/lib/mozilla):
WARNING: Please enter a valid installation path.

4)At this stage press CTRL+C and have a look at your mozilla installation directory. It by default take directory as /usr/lib/mozilla. Based on system you use it may vary. Like /usr/lib/firefox-2.0.0.3 or others. In my system to see I used,
debian:# ls /usr/lib/moz*
/usr/lib/mozilla:
libflashplayer.so plugins

/usr/lib/mozilla-firefox:
components plugins

/usr/lib/mozilla-snapshot:
plugins

So my installation directory is /usr/lib/mozilla-firefox. I have to provide this path whenever it prompts.

5)Again start the installer and provide this path.
debian:# ./flashplayer-installer
Please enter the installation path of the Mozilla, Netscape,
or Opera browser (i.e., /usr/lib/mozilla): /usr/lib/mozilla-firefox

WARNING: The Adobe Flash Player binary is a symbolic link.
The installer will replace this symbolic link with the actual binary.
