Disabling the Google new tab page

After installing Google Toolbar, Whenever you press Ctrl+T or go for a new tab, a page will be displayed by it. (see the below picture)

To disable it, there are two ways. I will explain both.
First method
1. click the settings icon in the google toolbar .
2. In the web-browsing uncheck the option "Enable Google new tab page".
3. click save.

Second method (This works only in Firefox)
1. Type "about:config" in the URL
2. A page will appear asking for confirmation to proceed (Sometimes it will not ask, dont worry about that)
3. The configurations will be displayed.
4. Type "newtab" in the filter bar
5. It will show a string named "google.toolbar.newtab"
6. Double click that to set the value to false.
