Google loves to get creative with its logo on holidays and special occasions by customizing their logo for a day. But what if you love one of those logos so much that you want to keep it all through the year.

Favorite doodle is a Greasemonkey script, which though developed by a Google employee,  is not an official google project. You can download the script from http://code.google.com/p/gmsearchscripts/.

Once installed you can browse the gallery of all Google logos (google.com/logos)for all the past Google logos, dating back to the year 1998. Once you find your favorite doodle, just click on the “Make This My Favorite Doodle” button below the logo and you will be redirected to the Google homepage, now showing your favorite doodle instead of the regular Google logo.

By default, your favorite doodle will be overwritten by any special doodle that Google assigns for that day so that you never miss any new ones. But you can change this in the options.

Requirement: Firefox, Greasemonkey
