Browser Extension

I need a simple browser extension for chrome. It must do the following things:

1) have a user sign-in with username and password and verify user info against a SQL database. keep the user signed in even after closing the browser. Have a logout button once signed in.

2) when the extension detects you are on a specific site have it overwrite & autofill info into a sign-in form using database information only if the user hasn’t exceeded the maximum number of active sessions allowed by the database.

3) display users active sessions for that site in the extension.

4) once user signs into site track users active sessions on the site and report back to the SQL database and close sessions once the user leaves the site or clicks to sign out on the site

5) when a user deletes the extension open up a specific page
