Description
Use the chrome.pageCapture API to save a tab as MHTML.
Permissions
pageCapture

MHTML is a standard format supported by most browsers. It encapsulates in a single file a page and all its resources (CSS files, images..).

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.

Manifest #

You must declare the "pageCapture" permission in the extension manifest to use the pageCapture API. For example:

{
  "name": "My extension",
  ...
  "permissions": [
    "pageCapture"
  ],
  ...
}
