create a file that opens a url

[Gentian Hila <genti tech gmail com>]

Hi,

I created a text file that opens a url like this with gedit:

firefox http://www.something.com

Changed the permissions to execute but when I double click I see a
window that asks me if I want to run in terminal or cancel or run the
program.

I want to make it open that website immediately as I double click the file.

How can I do that ?


Thank you
