Question getting a strange error


hello
I am new here and fairly new to linux and just did my first install I went with kubuntu 8.10 and I installed firefox 3.1b3 (shiretoko from repo) when I open fx I get "java script application" in the title bar and "reference error, nsbrowserstatushandler is not defined" when I close the browser and re-open it I get " firefox is already running in another application you must close it or re-start your computer" I have googled it, read books at the store and I can find nothing about this anywhere? any help out there?

My suggestion is to kill the runaway firefox process:

In a terminal type this code ps -Al | grep firefox

It'll return the PID number of any firefox process running, so you can then kill it

Here's a sample output, what I typed is in bold, the PID number is red
Code:
tred@vaio:~$ ps -Al | grep firefox
0 S  1005  6593  6417  0  80   0 -   443 -      ?        00:00:00 firefox-2
0 S  1005  6609  6605  2  80   0 - 41248 -      ?        00:00:30 firefox-2-bin
tred@vaio:~$ kill 6593
tred@vaio:~$ kill 6609
tred@vaio:~$ ps -Al | grep firefox
tred@vaio:~$                   <- See? No firefoxes are running now
Then try restarting firefox from the terminal, so you can see any error messages. I am not sure what your firefox is called, so we'll let bash help us with auto-completion. In this next bit of code <TAB> means "Press the TAB key on your keyboard", the rest of the firef____ will be auto completed, then just press <RETURN> so you'll know what it is called
(as you can see mine is firefox-2 so that's what I type to start it)
Code:
tred@vaio:~$ which firef<TAB><RETURN>
/usr/bin/firefox-2
tred@vaio:~$ firefox-2
And welcome to LQ!

If you don't get the error when you start FF from the terminal, but you do when you start it from "the launcher", then there is something wrong with "the launcher".

Are you using KDE4.x ? If so, remember that it is still "under development" and buggy.

This is one of the many reasons I have stuck with kubuntu 8.04 - it's stable, supported and works well.
