firefox not launch in kubuntu

[erngab]

I use Kubuntu. Install Firefox.
Firefox does not start when it opens. Only the icon appears briefly in the taskbar at the bottom
I tried to run from start menu, the terminal, reinstall it - nothing.
Help someone !!!

Try running again in the terminal, but use the following:
firefox &

By putting the "&" at the end, errors will be output to the terminal. It may help figure out what's going wrong.

How did you install? From the repos using KPackageKit?

user@ubuntu:~$ firefox &
[1] 2282
user@ubuntu:~$ firefox&
[2] 2285
[1] Exit 1 firefox
user@ubuntu:~$ firefox &
[3] 2288
[2] Exit 1 firefox
user@ubuntu:~$ firefox &
[4] 2324
[3] Exit 1 firefox
user@ubuntu:~$

Install with `Firefox installer for Kubuntu` from start menu. Uninstall with KPackageKit and install from Terminal `sudo apt-get install firefox`.

I am having exactly the SAME problem. Firefox used to launch fine - I updated packages and now it Does the same as First poster.

Any help Would be GREAT, Thanks

First, see if you can get Firefox to open in Safe Mode. In the terminal, use firefox -safe-mode & and see if it opens. Maybe a plugin that's already installed is causing the problem.

If that doesn't work, try a local install. Download the Linux version from here:
http://www.mozilla.com/en-US/firefox/all.html

You should get a tar.bz2 file, which you can extract anywhere you'd like. I use ~/Applications/firefox

Inside of ~/Applications/firefox you need to run the firefox script. You can run this in terminal by using ~/Applications/firefox/firefox & and see if it will run.

If it won't, make sure you have all the required dependencies installed.

Please note that Linux distributors may provide packages for your distribution which have different requirements.

* Firefox will not run at all without the following libraries or packages:
o GTK+ 2.10 or higher
o GLib 2.12 or higher
o Pango 1.14 or higher
o X.Org 1.0 or higher

* For optimal functionality, we recommend the following libraries or packages:
o NetworkManager 0.7 or higher
o DBus 1.0 or higher
o HAL 0.5.8 or higher
o GNOME 2.16 or higher

Ah, so you had two versions installed at the same time? Silly 'buntu!
