Can't launch firefox

[Wraithfire]

well i just tried to update to firefox 1.5.0.2 with disatrous results it seems. the install wouldn't work, so i removed it and re installed mozilla-firefox, but now that won't work if i try to launch firefox i get:
Xlib: connection to ":0.0" refused by server
Xlib: XDM authorization key matches an existing client!

and if i try to launch mozilla-firefox:
Xlib: connection to ":0.0" refused by server
Xlib: XDM authorization key matches an existing client!

(firefox-bin:3957): Gtk-WARNING **: cannot open display:

any idea what's going here?

ok now when i run mozilla-firefox from terminal i get this:
Extension System Warning: Failed to set up default extensions files probably because you do not have write privileges to this location. While you can run Firefox like this, it is recommended that you run it at least once with privileges that allow it to generate these initial files to improve start performance. Running from a disk image on MacOS X is not recommended.

But the screen is blank, and i can't seem to run it as root or sudo; when i try i get:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(firefox-bin:4058): Gtk-WARNING **: cannot open display:

Which distribution do you use? What exactly did you do to install Firefox and then remove it?

I'm running Debian sarge, i tried to install firefox 1.5 using backports:
apt-get -t Sarge-backports install firefox
immediately after this, firefox stopped working. I realize i didn't remove the mozilla firefox first, so i tried that:
apt-get remove mozilla-firefox
but firefox1.5 still wouldn't work, so i tried manually removing the 1.5 install by deleting:
/usr/lib/firefox
following a post i read online somewhere (lost the page)
I've reinstalled mozilla-firefox:
apt-get install mozilla-firefox
which was not working at first, but now gives the extension system warning i posted last time and is EXTREMELY slow.

I ran this and thought i'd post it just in case it helps:

after some more searching i found libxpcom_core.so in /usr/lib/firefox :

You can do it like this:

ln -s /usr/lib/firefox/libxpcom_core.so /usr/lib/firefox/firefox-bin

Well i made the link with this result:
wraithfire@Hellfury:~$ sudo ln -s /usr/lib/firefox/libxpcom_core.so /usr/lib/firefox/firefox-bin
Password:
ln: `/usr/lib/firefox/firefox-bin': File exists

and firefox still won't launch

[falko]

Then try this:

ln -s /usr/lib/firefox/libxpcom_core.so /usr/lib/firefox/firefox-bin/libxpcom_core.so

[Wraithfire]

 ln -s /usr/lib/firefox/libxpcom_core.so /usr/lib/firefox/firefox-bin/libxpcom_core.so

Done, and i get back:

ln: accessing `/usr/lib/firefox/firefox-bin/libxpcom_core.so': Not a directory

symlinks are kinda tricky it seems
