how to recover my bookmark menu

Hey there! See the link for how to restore your bookmark menu for steps: https://support.mozilla.org/en-US/kb/restore-menu-bar-firefox Hope I helped! Kind regards, Bithiah!

In Firefox 87+ the Library and the Home button aren't present by default on the Navigation Toolbar and you need to drag them out of the Customize palette to the toolbar. You can drag the Bookmarks Menu button that shows the bookmarks in a drop-down list from the Customize palette to the Navigation Toolbar. *https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars See also: *https://support.mozilla.org/en-US/kb/use-firefox-sidebar-access-bookmarks-history-synced
