Disable "Most visited" in new tabs in Firefox 3

My standard browser is Firefox 3 because of its rendering, cross-platform availability and mostly because of its extensions. Some time ago I installed Google Toolbar to be able to see the page rank of websites I visit. Since then, every new tab I open took much longer to load than previously - I had to wait entering the URL I really wanted to visit to allow Google Toolbar to render 9 screenshots of my "most visited" sites. Well that's nice and all Google, but I've got shortcuts for those sites and even if I don't, I could possibly type their URL faster than it takes you to display this rather useless page in every new tab I open. So I went on a quest to disable this function and it's actually not hard at all!

To disable the “most visited” pages in Firefox with Google Toolbar, simply:

• Go to about:config
• Confirm the security question, if asked
• There’s a search bar at the top, enter “tab” here
• Scroll down to google.toolbar.newTab
• Double-click that line and notice that the right-side column has been changed to “False” and the row is now written in bold
• Close the about:config tab
