menus

The menus API first appeared in Thunderbird 66 (see bug 1503421). It is basically the same as the Firefox menus API, but modified to suit Thunderbird. Note that the similar contextMenus API will not be added to Thunderbird.

Use the browser.menus API to add items to the browser’s menus. You can choose what types of objects your context menu additions apply to, such as images, hyperlinks, and pages.

Permissions

menus

menus.overrideContext

Note

The permission menus is required to use menus.

Functions

create(createProperties, [callback])

Creates a new context menu item. Note that if an error occurs during creation, you may not find out until the creation callback fires (the details will be in runtime.lastError).

Parameters

createProperties

(object)

[checked]

(boolean)

The initial state of a checkbox or radio item: true for selected and false for unselected. Only one radio item can be selected at a time in a given group of radio items.

[command]

(string)

Specifies a command to issue for the context click. Currently supports internal command _execute_browser_action.

[contexts]

(array of ContextType)

List of contexts this menu item will appear in. Defaults to [‘page’] if not specified.

[documentUrlPatterns]

(array of string)

Lets you restrict the item to apply only to documents whose URL matches one of the given patterns. (This applies to frames as well.) For details on the format of a pattern, see Match Patterns.

[enabled]

(boolean)

Whether this context menu item is enabled or disabled. Defaults to true.

[icons]

(object)

[id]

(string)

The unique ID to assign to this item. Mandatory for event pages. Cannot be the same as another ID for this extension.

[onclick]

(function)

A function that will be called back when the menu item is clicked. Event pages cannot use this.

[parentId]

(integer or string)

The ID of a parent menu item; this makes the item a child of a previously added item.

[targetUrlPatterns]

(array of string)

Similar to documentUrlPatterns, but lets you filter based on the src attribute of img/audio/video tags and the href of anchor tags.

[title]

(string)

The text to be displayed in the item; this is required unless type is ‘separator’. When the context is ‘selection’, you can use %s within the string to show the selected text. For example, if this parameter’s value is “Translate ‘%s’ to Pig Latin” and the user selects the word “cool”, the context menu item for the selection is “Translate ‘cool’ to Pig Latin”. To specify an access key for the new menu entry, include a & before the desired letter in the title. For example “&Help”.

[type]

(ItemType)

The type of menu item. Defaults to ‘normal’ if not specified.

[viewTypes]

(array of ViewType)

List of view types where the menu item will be shown. Defaults to any view, including those without a viewType.

[visible]

(boolean)

Whether the item is visible in the menu.

[callback]

(function)

Called when the item has been created in the browser. If there were any problems creating the item, details will be available in runtime.lastError.

Return type (Promise)

integer or string

The ID of the newly created item.

Required permissions

  • menus

update(id, updateProperties)

Updates a previously created context menu item.

Parameters

id

(integer or string)

The ID of the item to update.

updateProperties

(object)

The properties to update. Accepts the same values as the create function.

[checked]

(boolean)

[contexts]

(array of ContextType)

[documentUrlPatterns]

(array of string)

[enabled]

(boolean)

[icons]

(object)

[onclick]

(function)

[parentId]

(integer or string)

Note: You cannot change an item to be a child of one of its own descendants.

[targetUrlPatterns]

(array of string)

[title]

(string)

[type]

(ItemType)

[viewTypes]

(array of ViewType)

[visible]

(boolean)

Whether the item is visible in the menu.

Required permissions

  • menus

remove(menuItemId)

Removes a context menu item.

Parameters

menuItemId

(integer or string)

The ID of the context menu item to remove.

Required permissions

  • menus

removeAll()

Removes all context menu items added by this extension.

Required permissions

  • menus

Parameters

contextOptions

(object)
