Google owns my web history

Another thread is tying me to my Google (Gmail) identity and to Firefox. I've given Google the right to track and record every web page I visit using Firefox with the Google toolbar installed and PageRank enabled:

Official Google Blog: Your slice of the web

...Today, we're pleased to announce the launch of Web History, a new feature for Google Account users that makes it easy to view and search across the pages you've visited. If you remember seeing something online, you'll be able to find it faster and from any computer with Web History. Web History lets you look back in time, revisit the sites you've browsed, and search over the full text of pages you've seen. It's your slice of the web, at your fingertips.

To get full value I have to use Firefox and the Google toolbar on every machine, and I have to be logged into Gmail. Quite a powerful connection ...
