From http://ashraful.org/browser-features/:

Nowadays almost any website you use has a lot of information about you. Google knows your search history, Microsoft has your emails, Facebook has your social graph and photos, Last.FM has your music history, Foursquare has your check-ins. And even though you are the owner, you cannot take your data with you.

You should be able to take your search history from Google with you, so you can use Bing and still get relevant results. You should be able to take your photos with you from Facebook to Google Plus so you can share it with your friends. You should be able to take your emails from Hotmail to Gmail so you can search through it more easily. And most importantly you should have the right to deny access to your data to any web service.

Browsr tries to provide you with complete control over your data by storing all our information locally. Instead of storing your information on some server that you don’t have access to, all of it is stored on your PC. And you can do whatever you want with it: back it up, put it on Dropbox, or provide access to any web service you choose. Having control over your data means you can quickly get started with new web services you want to use, with all your past data right there with you.

On top of that, Browsr also lets you keep your social connections with you by using the identity manager. Your entire social graph stays with you regardless of what social network you are using.
