I am currently re-setting up the apparmor profile for Firefox 19.0.2 on Ubuntu 12.04 and I am slightly confused.
In command line I wrote:
michael@ubuntu:~$ firefox
Firefox launched. Command prompt ($) disappeared.
Then I pressed ^+z.
The result was:
[1]+ Stopped firefox
Well, Firefox really stopped. It did not react anyhow. So, I could not close it by pressing the cross of the window. By the way, the menu items 'Tools', and 'Help' somehow showed some signs of life.
I have placed the map firefox in opt/.Now I want to place a symbolic link in /usr/bin.This is the output of my terminal:ecmporter@peek:~$ sudo -i
[sudo] password for ecmporter:
root@peek:~# ln -s /opt/firefox/firefox /usr/bin/firefox
ln: creating symbolic link `/usr/bin/firefox/firefox': File exists
root@peek:~# firefox
-bash: firefox: command not found
root@peek:~# sudo rm -r /usr/bin/firef
In Ubuntu lightdm log-in screen, guest session can be logged in without a password. Although guest gets lower privilege and can’t run sudo command, you can remove it from login screen via following way.
Edit LightDM configuration file “/etc/lightdm/lightdm.conf”. This need root privilege, use sudo nautilus command to start file browser with super user.
I compiled a short bash one-liner to focus a running application or launch it if it isn't running:
#!/bin/bash
#intellilaunch.sh
wmctrl -a $1 || $1 & disown
exit 1
The command exits perfectly fine when run directly from the command line:
:~$ wmctrl -a firefox || firefox & disown

A quick check with the system monitor shows that only firefox is running.
Mozilla is launching Firefox 16 today. While this version of the browser only introduces a few new features for consumers, developers can look forward to using Firefox’s new Developer Command Line.
Hi frinds !
I m a newcomer in Linux world.
I have just installed Ubuntu 13.04.
On some website I read about Firefox20. So I want to upgrade my firefox. But in help there is
one step in that I have to move firefox directory ( which actually came after extracting file firefox-21.ob7.tar.bz2)
to /opt folder.
recently I had deactivated lightdm since I don't want the Desktop Environment running and consuming RAM.
To accomplish that I had override the lightdm by creating the file:
#echo "manual" >/etc/init/lightdm.override
I would like to open some applications like firefox...
I want to type firefox in terminal and run Mozilla browser.
So I try to create sym-link:
ln -s /opt/firefox firefox
but after typing firefox in terminal I get an error: bash: firefox: command not found
Where is problem?
