// @description    In vanilla Firefox, `browser.tabs.loadBookmarksInTabs` only affects bookmark items. When you enable this pref and left-click a bookmark (e.g., in the bookmarks toolbar or menu) it opens in a new tab instead of in the current tab. But if you left-click a history entry or a synced tab, it will still open in the current tab. So you'd have to middle click or ctrl+click to avoid losing your current tab's navigation state. This script just makes that preference apply to history and synced tabs too.
