menus.ContextType

Values of this type are strings. The item is displayed when the given context applies. Possible values are:

all

Specifying 'all' is equivalent to the combination of all other contexts except for 'bookmark', 'tab' and 'tools_menu'.

action

Applies when the user context-clicks your browser action in a Manifest V3 extension. The maximum number of items that can be added to the top-level browser action context menu is menus.ACTION_MENU_TOP_LEVEL_LIMIT, but you can add any number of items to submenus.

audio

Applies when the user context-clicks an audio element.

bookmark

Applies when the user context-clicks a bookmark item in the bookmarks toolbar, bookmarks menu, bookmarks sidebar (Ctrl+B) and the Library window (Ctrl+Shift+B). The latter two are supported as of Firefox 66. Requires the "bookmarks" API permission in the manifest.

browser_action

Applies when the user context-clicks your browser action in a Manifest V2 extension. The maximum number of items that can be added to the top-level browser action context menu is menus.ACTION_MENU_TOP_LEVEL_LIMIT, but you can add any number of items to submenus.

editable

Applies when the user context-clicks an editable element, like a textarea.

frame

Applies when the user context-clicks in a nested iframe.

image

Applies when the user context-clicks an image.

link

Applies when the user context-clicks on a link.

page

Applies when the user context-clicks in the page, but none of the other page contexts apply (for example, the click is not on an image or a nested iframe or a link).

page_action

Applies when the user context-clicks your page action. The maximum number of items that can be added to the top-level page action context menu is menus.ACTION_MENU_TOP_LEVEL_LIMIT, but you can add any number of items to submenus.

password

Applies when the user context-clicks on a password input element.

selection

Applies when part of the page is selected.

tab

Applies when the user context-clicks on a tab (specifically, this refers to the tab-strip or other user interface element enabling the user to switch from one browser tab to another, not to the page itself).

From Firefox 63, clicking the menu item on a tab grants the activeTab permission for the tab clicked, even if that isn't the currently active tab.

tools_menu

The item will be added to the browser's tools menu. Note that this is only available if you access ContextType through the menus namespace. It is not available if you access it through the contextMenus namespace.

video

Applies when the user context-clicks a video element.

Note that "launcher" is not supported.
