Why/User Benefit/User Problem

Focus is a browser that is meant to be private and also (implicitly) fast. We should make it easier for users to access common features in Fenix that allow it to be so.

What / Requirements

Long-pressing on the toolbar provides the user with quick actions they can perform.

Acceptance Criteria (how do I know when I’m done?)

Having the same/similar quick actions as Fenix does when you long press on the browser toolbar.

Example:

For a bit of context regarding Fenix this was implemented in https://github.com/mozilla-mobile/fenix/issues/4155 and https://github.com/mozilla-mobile/fenix/issues/6846. The ToolbarPopupWindow that is used would probably have to be shared through A-C a refactoring which would also present the opportunity to reimplement it in Compose.
