1357651 - contextMenus.create does not support CSS selector context

Status: RESOLVED DUPLICATE of bug 1341804

(WebExtensions :: Frontend, enhancement)

Description

[Frédéric Wang Nélar]

The current contextMenus API does not seem to contain any way to create an item based on a CSS selector context. Only some specific cases like images, audio or iframes are supported [1].

The old addon-sdk API had a more powerful set of declarative context, including SelectorContext(selector) for that purpose: 'This context occurs when the menu is invoked on a node that either matches selector, a CSS selector, or has an ancestor that matches. selector may include multiple selectors separated by commas, e.g., "a[href], img".'. I would be nice to have something similar for WebExtensions.
