What is the output of:

sudo fullupgrade; lsb_release -a; uname -a; locate firefox-bin

Thanks

This is the output I got in the terminal

russell@russell-Presario-V6000:~$ sudo fullupgrade; lsb_release -a; uname -a; locate firefox-bin

I've been using another command to execute the firefox program , it is "Pkill firefox"

ok try:

sudo updatedb; locate firefox-bin

What is output please?

Nothing happened when I typed that command in :-

russell@russell-Presario-V6000:~$ sudo updatedb; locate firefox-bin
russell@russell-Presario-V6000:~$

I opened up firefox to test it with the "killall firefox-bin" command and I still got this :-

russell@russell-Presario-V6000:~$ killall firefox-bin
firefox-bin: no process found
russell@russell-Presario-V6000:~$

Maybe I have to stick to using "pkill firefox" as this command does the same thing as that one, I looked in both files as to where the firefox-bin script is supposed to be (2 different people said Iceweasel & firefox directory) and it's not there,as if it has been deleted.

Hmmm, can you give the output of:

apt-cache policy firefox; ps -ef | grep -i fire

Thanks

Well, I that in and this is the output I got :-

russell@russell-Presario-V6000:~$ apt-cache policy firefox; ps -ef | grep -i fire

I still got this :-

russell@russell-Presario-V6000:~$ killall firefox-bin
firefox-bin: no process found
russell@russell-Presario-V6000:~$

It seems to me that there was some misunderstanding. I try to shed some llight on a number of items:

The executable file firefox-bin is installed as part of the firefox package for the versions up to firefox 4.0.
It is no more existing in higher versions like 11.0 which is installed on your system.

A command like 'killall firefox-bin' searches the list of running processes and terminates each process that is running the firefox-bin command.

If killall does not find any process running that executable, it comes back with the message 'no process found'.

The aim of the killall command is terminating processes, not to start a new one. If you want to start a firefox process, you have to execute the 'firefox' command, not 'killall firefox'.

We do not know what the background of the internet page mentioned in your question is, so we cannot tell what the current equivalent of that command would be, now when firefox-bin does no nore exist. What I can imagine is the following background: If you do an update to the firefox package you should make sure, that there is no process using the firefox executable files. You can stop all processes runing firefox with a killall command. If no process is running firefox, the killall command will give a warning, but that does not matter, as the aim of 'make sure no firefox process is running' has been achieved anyhow.

And one last remark: The maverick (10.10) release of Ubuntu that you are running has already been declared end of life by April 10, 2012. You should consider upgrading to a supported release. see https://wiki.ubuntu.com/Releases

Maverick is now EOL, no updates or support. I suggest you clean install with Precise (Ubuntu 12.04)
