Wallet for Safari installs a button in your browser`s toolbar for letting you access the Wallet service directly from the current page..
The aim of the Wallet`s extension is to help you autofill forms on any web page using your Wallet data. You can also save new passwords directly to Wallet. Just click the toolbar button, type in your Wallet password, and you`re ready to go.
Browser extensions are available for both Safari and Google Chrome. They are made using standard web technologies, so you will never have to worry about them breaking when you update your browser.
