A lot of people don't realize that their browser home page does not have to be out on the web somewhere. It can be right on your computer; just create an HTML file which will reside on your computer and specify your browser homepage as that file.

Here's part of one admin's home page, with links to her Drupal sites' maintenance tasks (cPanel, FTP, etc.) included, so she doesn't have to keep looking them up.

She also included links to her test sites, so they are easy to get to as well.

Configure the browser Startup to "Show my homepage" not to "Show my windows and tabs from the last session". That way, it should always start up by displaying the home page you specify.
