I want to open a web page and execute javascript code simultaneously and by one click on the URL part of a bookmark in Mozilla Firefox. Could anyone suggest a solution for it? In fact, I want to create a bookmark containing a web page address and javascript code.

For example: The web page "http://www.google.com" is opened and a message containing "Hello World" is displayed on the screen only by one click. In fact, both of the aforementioned things should be done simultaneously and by one click not separately.
