You can configure the Google Chrome browser so that when you open it instead of showing just your home page, it can show multiple pages all in their own tab.

To get Chrome to do this click on the wrench icon in the top-right part of the browser and select Options from the menu.

Once the options open, get to the Basic tab.

You want to check the radio button next to Open the following pages:.

You can then click the Add... button to add pages to be opened when you start Chrome.

There is also a button called Use Current that will add all of your currently open tabs to the list of pages to be opened. So a good strategy to avoid entering a lot of URLs is to get your browser how you want it when it starts, then click this button.
