I followed the instructions and they worked perfectly!
Download and install Suse – install it into the /opt directory.
You should find a file called firefox in the installation directory (i.e. /opt/firefox/firefox).
Now you have two choices:
1) Add the installation directory to the path
2) Create a symbolic link for firefox from /usr/bin to the install directory (this is the way I used). The command in my example is: ln -s /opt/mozilla/firefox/firefox /usr/bin/firefox
Now you can just type ‘firefox &’ in a terminal or the Run command to start it.
You will need to set up shortcuts and start menu items for yourself, this is very easy.
You will find nice icons for firefox in the firefox installation directory under icons (i.e. /opt/firefox/icons/).
To add firefox to the KDE toolbar:
1) right click on the toolbar.
2) Select: Panel Menu -> Add -> Special Button -> Non-KDE Application
3) Enter the location of the executable: /usr/bin/firefox
4) In the next box it says ‘Optional command line arguments’ and there is an icon next to it. Select the icon and you can change it by browsing to the firefox icons in the install directory.
To add it to the Start menu, simply right click on the start button and
select ‘Menu Editor’, the rest should be obvious.
Hope this helps others – thanks Brian.
