Ubuntu Warning!!!!

I just received the ugliest warning I have ever seen in Ubuntu

here is a screenshot.




So the warning is telling me that Firefox is already running. in other words it was not shut down properly and now is stuck in memory limbo ( not exactly technical description ) but you know what I mean. Sorta like when a program stops responding in windows and you cant seem to get it to shutdown.

That is not my issue here, what really bothered me was that it also says that I may need to restart my system. " Restart my system??? " what? are you kinding? this is linux not windows.

We do not restart our systems when a program stops responding. We kill the process.

Step 1: open a terminal
go to Applications > Accessories > Terminal

Step 2: find the pid
Type ps aux | grep firefox
you should get a couple of lines that look like this.

idleone 24732 7.5 9.3 217228 96388 ? Sl 09:30 0:52 /usr/lib/firefox-3.0/firefox
idleone 24959 0.0 0.0 3004 748 pts/0 R+ 09:42 0:00 grep firefox

Step 3: kill the process
the pid number is the first set of numbers at the beginning of the line. in this case 24732

type kill 24732

If you prefer the GUI ( Graphical User Interface )

go to System > Administration > System Monitor.

Click on the Processes tab, find the process you want to kill and click End process.

and there you have it, you have just killed Firefox and can now restart it.

NO NEED TO RESTART YOUR SYSTEM. We don't run Windows.
