About a week ago, I accidentally deleted all of the passwords that were stored in Firefox. So I have been manually reentering the passwords for each of the sites that I visit. If Firefox used the Keychain, this would be less of a hassle as the passwords would just be stored there.
Camino is a Gecko based web browser, that has a lot of the support for the Mac OS X features. It integrates with the Keychain, Address Book and Spotlight.
The one potential downside is that it doesn't support the collection of Firefox extensions. This is not really an issue since it has built-in support for blocking ads and popups.
I am now running Camino browser as my default.
