Question

I have a greasemonkey user script with this single line of code…

window.close(); 

but firefox does not allow a user script to close a window (as reported by an error message in the error console)

Is there a work around to this problem?

Answer 1

You need to change configuration settings of Firefox (about:config) to allow this.

Steps:

1. Go to address bar and type about:config
2. Go to parameter dom.allow_scripts_to_close_windows
3. Set its value as true

Now your script can close the TAB with ‘window.close()’

eg.

function closeTab(){     window.open('', '_self', '');     window.close(); }
