Enable backspace to take you to the previous page in firefox

For a change, a small tip for people who use keyboard shortcuts for navigation in the web browser. I've been using this feature in IE and Safari. I recently noticed that this doesn't work by default in firefox (Ubuntu). To enable this feature, open a firefox window and type 'about:config' (without the quotes). Search for 'backspace' in the filter tab. The only entry for backspace will be 'browser.backspace_action'. Right click on it and modify the entry to '0' from the default value. There you go. Now, you can use backspace to go to the previous page/s you were viewing.
