Enable All Tabs Previews In Firefox 4

Mozilla has work hard on their new Firefox 4. Here I am going to show you how to enable Firefox All Tabs Previews which is not enabled by default. If you want to see this, follow the following instruction.


First open a new tab. Now type about:config in the addressbar. Click the 'I'll be careful. I promise!'. Now copy paste this to the about:config search box> browser.allTabs.previews


There should be only one result. Double click it to toggle it to true. Now you should see a button on the caption title. Click it and all of your tabs will be showed as thumbnails.
