Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, enhancement, P2)

Description

[Emma Zühlcke [:emz]]

The service nsICookieBannerService will be initialized on startup and manage the following components for handling cookie banners:

• nsICookieBannerRule / nsICookieRule / nsIClickRule: Rules containing instructions on how to handle cookie banners for a specific site.
• nsCookieInjector: Inject / preload cookies based on rules in order to suppress cookie banners.
• nsICookieBannerListService: Imports cookie banner handling rules and sync them with the nsICookieBannerService on update.

nsICookieBannerService should have methods for querying banner handling rules by domain or URI.

This patch adds the following components:

• nsICookieBannerService: Main service singleton managing the rules and initiating other components.
  It's exposed via Services.cookieBanners and can be configured via the cookiebanners.* prefs.
  To enable it set "cookiebanners.service.mode" to 1 or 2 and restart the browser.
• nsCookieInjector: Looks up rules and injects cookies for matching top level loads.
• nsICookieBannerListService: Imports and updates the cookie banner rules.
• nsICookieBannerRule: Rules for a given domain.
• nsICookieRule: Part of nsICookieBannerRule. Holds cookie specific rules.

Depends on D153641
