chrome.pagueCapture

Description

Use the chrome.pagueCapture API to save a tab as MHTML.

MHTML is a standard format supported by most browsers. It encapsulates in a single file a pague and all its ressources (CSS files, imagues..).

Note that for security reasons a MHTML file can only be loaded from the file system and that it can only be loaded in the main frame.
