I have two Firefox versions! help.

Hi Folks

I've messed up a little by not understanding how the file system works in Linux (Suse 10.0). I installed Firefox 2 by downloading a file, extracting it and placing the 'firefox' folder in home/adrian./mozilla

This worked nicely and I added my old bookmarks and addons and all worked nicely. However, the mplayer plug-in won't work. I have spent most of today trying to get Mplayer itself to work (now solved, old version of x264 installed) and then tried to get the plug-in working. (NB I used Yast for the above.) The plugin won't work in Firefox though and this is when I realised that I've messed up firefox.

As a user, if I open Firefox I get Firefox 2 with all my bookmarks, plugins and themes in place. However, the mplayer plugin (or RealPlayer one) won't work.

If I log on as root, I open Firefox using the desktop shortcut (or a command in a terminal) and get Firefox version 1.5 with default bookmarks. In this version of Firefox, the Mplayer plugin works perfectly well. This isn't a Firefox fault as my version 2 doesn't even know that mplayer is a plugin!

Reading another thread I typed in to a terminal 'which firefox' and got the following reply:

I get this reply if I type this into a terminal as root or as user.

So, my installation of Firefox 2 obviously sucked. What did I do wrong, and perhaps more importantly, how do I put it right? Do i have to uninstall everything?

It seems to me like you just need to copy your Firefox 1.5 plugins to your Firefox 2 plugin directory.

I have sort of solved this, but can't sort out plugins.

I uninstalled Firefox 1.5 with YaST and this no longer runs.

I then copied the folder 'firefox' from my user folder to /usr/local/

I followed the advice I found on Google and did the following:

bash# cd /usr/local/bin
bash# ln -s ../firefox/firefox .

Now Firefox 2 is the default version for all users - Yippee!!!

However, no matter what I do i can't get the mplayer and some other plugins to work. I have worked on this problem for several hours now and no matter where i put the files, the mplayer (or Flash 10) plugin isn't recognised by Firefox.

I have put the files

mplayerplugin-so and
mplayerplugin.xpt into the following folders:


But still no good! Oddly though, the Adobe Flash version 9beta that I installed before i got into this mess still works fine - all YouTube videos play nicely with this.


Any ideas before I go mad?

Several more hours and still no solution....

However, I tried again to install mplayerplug-in
I first uninstalled with YaST and then tried to install it manually. Here's what I got:

The WARNING messages look appropriate... but can anyone help explain them?
