// Glue between autoconsent (inlined above by build-inject.js) and the add-on.
|
||
|
|
// Runs in the isolated world of every http(s) frame. Nothing is exposed to
|
||
|
|
// the page: the library works through the DOM only, and the few rules that
|
||
|
|
// need the page's own JavaScript go through theseus.evalInPage.
|
||
|
|
//
|
||
|
|
// Message flow (see autoconsent docs/api.md): the instance asks for "init",
|
||
|
|
// the add-on answers with the user's settings and the rule bundle (or
|
||
|
|
// nothing, when the add-on is off or the site is excluded); "eval" requests
|
||
|
|
// are run in the main world and answered; the outcome messages are reported
|
||
|
|
// so the panel can count handled pop-ups per site.
