 # Unofficial Blockstack Extension
 
-This is a web extension to add Blockstack support to the Web Browser by making it so a user can log into the browser and authenticate apps via popup windows instead of through https://browser.blockstack.org/ or having to run their own instance of the Blockstack Browser. This makes the experience much more native and easy to use!

-Currently you can not edit your profile or manage your wallet. This is more of a proof of concept then a finished product, and it may have bugs; use it at your own risk!
