How to install plugins for Firefox

Release 1.0 July 25 2005

Intro: Mozilla is an Opensource product inherented from Netscape. And again Firefox is a "light" product of Mozilla, it works just like an ordinary browser, no more no less like the Mozilla Suite.
To install plugins for Firefox is dead-easy if you know how to do. All the supported plugins for Firefox can be freely download from Firefox plugins.

Let start: From Fedora3 it is easy to install Firefox from the CDROM with the rpm command, but for the old versions of FC/RH/Linux you need download it from the net. At that point the dependencies can work against you. So the fast&easy way to install Firefox for alle the users is to get an installed file with include all the dependencies. The file can be found at Firefox Installer, pick up the "Linux i686" version.
a) Unpack it to /tmp: tar xvzf firefox-1.0.6.installer.tar.gz -C /tmp
b) execute /tmp/firefox-installer
c) let the installer installs it at the directory /firefox-installer
d) put the next line at the second line at /etc/profile (the global path for all users, giving the users access to the Firefox binary) or at your homedir ~/.bash_profile

Done, now you can start your browser by enter "/firefox-installer/firefox"...A browser without any plugins can be userless nowadays, let install some.

Install plugins for Firefox:

1) Get the Macromedia Flash Player from Unpack the file with tar xvzf install_flash_player_7_linux.tar.gz -C /tmp
a) get the 2 packages "ttfonts" and "urw-fonts" from "" or from the cdrom, install those with rpm -Uvh <name of the package>
b) execute /tmp/install_flash_player_7_linux/flashplayer-installer (ignore the Note about the font packages)
c) at the question about the fold of firefox, just enter /firefox-installer (I assumed you have firefox at the directory /firefox-installer)

NB: for the new Flash10 please do:
a) rpm -ivh <the flashplayer package> (get the package from
b) ln -s /usr/lib/flash-plugin/ /usr/lib/firefox/plugins

Test: type "about:plugins" at the address bar after restarting firefox, you will get a section called "Shockwave Flash" with 2 MIME Types.

Troubleshooting: remember to put all the "execute" parts from the plugins in your working path. It means at the second line of your /etc/profile, you must have this line.
