Answer 1

A bit more gentle

As @skybert indicated in the comment, you can

set browser.sessionstore.resume_from_crash to false.

in about:config, which

will rid you of the "Ups, something went wrong ..." message.

To get rid of the safe-mode message, you can set the config

toolkit.startup.max_resumed_crashes to -1

or (just set) the environment variable MOZ_DISABLE_AUTO_SAFE_MODE.

Less gentle

In lack of a better solution, you can remove sessionstore.js from the profile folder after the killall.

This is no more "gentle" than your solution, but it fixes the "Safe Mode" message:

Answer 2

You can first get the Pid of firefox with

pgrep firefox

and after use kill to stop firefox kill [pid]

kill `pgrep firefox`

Answer 3

First Run xkill command after that click on window which one you want close

    xkill

Answer 4

In Mac OS X, you could use AppleScript to close it (adjust the application name as necessary; I don't have FireFox installed to test):

$ osascript -e 'tell application "FireFox"
quit
end tell'

This should trigger the same event that the Quit menu command triggers, so FireFox should shut down cleanly.

Obviously, this won't work in Linux.

Answer 5

You can use pkill with the process name:

pkill -f firefox

Answer 6

How about

wmctrl -c "Mozilla Firefox"

?

Is it what you want?

NOTEs:

1. This command may need to be fired in same DISPLAY & probably same virtual desktop, on which your firefox is running.
2. Only first matching window will be closed. You may need to loop this command.
