If you'd like to have a Google Start Menu, (the unofficial) GUtil for Firefox could help you a little. The extensions adds on your navigation toolbar a big list of Google services. Instead of trying to find the name of the service in the list, you can just type the first letters from the name (typing "r" opens Google Reader).The list is customizable, and might be a good way to open a certain Google site, instead of going to another page that contains the list.
