Opening a New Firefox Tab

I have set Firefox to open new links (links I often select from emails) in a new tab. About half the time, Firefox opens the link with the cursor at the very bottom of the newly opened page and I then have to click on the page and press Command-UpArrow to get to the top of the page in order to start reading the linked article. How can I use keyboard maestro to move to the top of the page every time Firefox opens a new link?
