Hide all default Firefox menu items in favor of providing a custom context menu UI.
The overrideContext method will cause the matching menu items from this extension to be shown instead of the default menu. This method should be called from a
contextmenu
DOM event handler, and only applies to the menu that opens after this event.
This interface requires the
menus.overrideContext
permission
.
browser.menus.overrideContext(
contextOptions
// object
)
contextOptions
对象
. Options for how the context menus will be overridden.
showDefaults
可选
boolean
. Whether to also include default menu items in the menu.
context
可选
string
. ContextType to override, to allow menu items from other extensions in the menu. Currently only
'bookmark'
and
'tab'
are supported.
showDefaults
cannot be used with this option.
bookmarkId
可选
string
. Required when context is
'bookmark'
. Requires 'bookmark' permission.
tabId
可选
integer
. Required when context is
'tab'
. Requires 'tabs' permission.
Open the tab context menu on your custom UI, in this case :
document.addEventListener('contextmenu', event => {
const foo = event.target.closest('.foo');
if (foo) {
// When the context menu is opened on an element with the foo class
// set the context to "opening a tab context menu".
browser.menus.overrideContext({
context: 'tab',
tabId: parseInt(foo.dataset.tabId)
});
}
}, { capture: true });
