Ubuntu – Close current tab firefox using terminal

command linefirefox

I have firefox already running on my system, and now in minimised state. What I want is to close the current tab running in firefox. How can I do this by simply using commands in terminal?

Best Answer

To keep Firefox minimized after closing its current tab (according to OP, see the comment) use the following commands in a terminal,

wmctrl -a firefox; xdotool key Ctrl+w; wmctrl -r firefox -b add,shaded

How it works

wmctrl -a firefox

Go to the window with a name containing 'firefox' in it

xdotool key Ctrl+w

Send the keystroke Ctrl+W to firefox which is the shortcut to close current tab in firefox.

wmctrl -r firefox -b add,shaded

Shade a window with a title that contains the word 'firefox' in it.

To know more about these see man xdotool and man wmctrl

Alias for above command

You can make an alias for the above commands, say the alias name be cfct ( Close Firefox Current Tab) in ~/.bashrc or better in ~/.bash_aliases from a terminal as,

echo -e "\nalias cfct='wmctrl -a firefox; xdotool key Ctrl+w; wmctrl -r firefox -b add,shaded'" >> ~/.bash_aliases
. ~/.bash_aliases

If you don't have ~/.bash_aliases replace ~/.bash_aliases in the above commands with ~/.bashrc

Usage

open a terminal and enter

cfct

And it will close Firefox’s current tab instantaneously.

Note: You need to have wmctrl and xdotool installed in your system. To install them use,

sudo apt-get install wmctrl xdotool
