That notion has helped to rekindle the browser wars and has resulted in the latest wave of innovation. Firefox 3.0, for example, runs more than twice as fast as the previous version while using less memory, Mozilla says.
The browser is also smarter and maintains three months of a user's browsing history to try to predict what site he or she may want to visit. Typing the word "football" into the browser, for example, quickly generates a list of all the sites visited with "football" in the name or description.
Firefox has named this new tool the "awesome bar" and says it could replace the need for people to maintain long and messy lists of bookmarks. It will also personalize the browser for an individual user.
"Sitting at somebody else's computer and using their browser is going to become a very awkward experience," said Mitchell Baker, chairwoman of the Mozilla Foundation.
