Ever try closing a series of tabs in Firefox by hitting Ctrl+W over and over until you were down to your last tab? Ever overshoot and accidentally wind up closing the whole browser and then having to wait (im)patiently to reload the browser?

There's a setting tucked away in the recesses of Firefox 3.5's configuration options that will keep the browser running after you close the last tab. Instead of closing, Firefox will simply display a single blank tab.

Here's how it works. Type "about:config" into the location bar (without the quotation marks), and then finding the setting labeled "browser.tabs.closeWindowWithLastTab" (again, without the quotes) and double click that setting to change the value to false. That's it. Now when you close all your browser tabs Firefox will stay open.

Just follow these easy steps to get started:

1. 

   Start the process by clicking Run.

   Depending on your connection speed, the download may take up to a few minutes. Thanks for your patience¡­ it¡¯ll be worth the wait!

2. 

   Click Run to launch the Mozilla Firefox setup wizard.

   Then, just follow the steps (we¡¯ve made the process as painless as possible).

3. 

   Now you¡¯re ready to leap boldly into a new era of Web surfing.

   Double-click on the Firefox icon whenever you want to go online.
