The script does not work with Chrome under Ubuntu (Unity)

[ghost]

When running the script under Ubuntu 16.04 running Unity the chrome browser opens with the URL. The save dialog box appear. But then the "Type your command" popup appears as if ALT key is pressed. So the full path gets added to the command box instead of the save dialog and the dialog does not close. It's caused by the fix done for issue #1.
If the above issue is fixed, after saving the page, when the tab close (ALT+F4) is invoked, it is changing to text mode as if (CTRL+ALT+F4) is pressed.

I have fixed both the issues but tested only in Ubuntu 16.04. Will send the PR.
