Although this add-on uses a stored password to authenticate to a web server,
it should not be taken as an example of how to store or work securely with
passwords. It's only a demonstration of how to use the
webRequest.onAuthRequired API.
This add-on uses the webRequest.onAuthRequired API to log the user into
the demo site at https://httpbin.org/basic-auth/user/passwd using a stored
username and password.
This add-on stores a username and password using the storage.local API.
The default value is the correct value
for the demo site:
username: "user"
password: "passwd"
You can change the default values in the add-on's options page.
The add-on then uses webRequest.onAuthRequired to intercept authentication
requests from the demo site. When it gets
such a request, it fetches the stored credentials and supplies them
asynchronously.
To try out the add-on:
- Before installing the add-on, visit https://httpbin.org/basic-auth/user/passwd, and see that it asks for a username and password.
- Install the add-on in Firefox 54 or later.
- Visit https://httpbin.org/basic-auth/user/passwd again, and see that authentication succeeds automatically.
