# WebExtensionBrowserMenuBuilder

`class WebExtensionBrowserMenuBuilder : `[`BrowserMenuBuilder`](../-browser-menu-builder/index.md) [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/browser/menu/src/main/java/mozilla/components/browser/menu/WebExtensionBrowserMenuBuilder.kt#L29)

Browser menu builder with web extension support. It allows [WebExtensionBrowserMenu](../-web-extension-browser-menu/index.md) to add
web extension browser actions in a nested menu item. If there are no web extensions installed,
the web extension menu item would return an add-on manager menu item instead.

### Parameters

`store` - [BrowserStore](../../mozilla.components.browser.state.store/-browser-store/index.md) required to render web extension browser actions

`webExtIconTintColorResource` - Optional ID of color resource to tint the icons of back and
add-ons manager menu items.

`onAddonsManagerTapped` - Callback to be invoked when add-ons manager menu item is selected.

`appendExtensionActionAtStart` - true if web extensions appear at the top (start) of the menu,
false if web extensions appear at the bottom of the menu. Default to false (bottom).
