	sidebar-bookmark-list.css	The base fxview grid template assumes a multi-column tab list; the sidebar is a single shrink-to-fit column. Use minmax(0, 1fr) on both explicit and implicit tracks so rows can shrink below their min-content width and the row text actually truncates with text-overflow: ellipsis.	5617	-
	sidebar-bookmark-list.mjs	A row in the sidebar bookmarks tree. @typedef {object} SidebarBookmarkItem @property {string} guid @property {string} title @property {string} [uri] @property {string} [url] @property {string} [icon] @property {number} type @property {SidebarBookmarkItem[]} [children] @property {boolean} [isPlaceContainer] @property {boolean} [isTagContainer] @property {boolean} [isTagsRoot]	25569	80 %

	sidebar-panel-header.css	Horizontal-tabs "hide-launcher" mode has no launcher to switch panels with, so the title is replaced by the sidebar-panel-switcher dropdown (which shows itself in this mode).	884	-
	sidebar-panel-header.mjs	Shared header showing the panel title and a close button. In horizontal-tabs "hide-launcher" mode the title is replaced by the sidebar-panel-switcher dropdown (which switches between panels), since there is no launcher to switch them with; this is toggled via CSS (see sidebar-panel-header.css).	3324	96 %
	sidebar-panel-switcher.css	The switcher is only meaningful in "hide-launcher" mode, where there is no launcher to switch panels with. It hides itself everywhere else.	1908	-
	sidebar-panel-switcher.mjs	A dropdown that switches between sidebar panels. Used by panels in horizontal-tabs "hide-launcher" mode, where there is no launcher to switch panels with. The element shows the current panel's name and, on click, lists the other panels to switch to. It hides itself (via CSS) outside that mode. Built-in panels set the `view` attribute to the command ID of the panel hosting it. Extension panels leave it unset, so they are identified by whichever panel the sidebar currently has open instead.	3007	100 %

	sidebar-pins-promo.mjs	A promotional card for drag-to-pin tabs. It is only displayed in the expanded sidebar state to vertical tab users who do not have any pinned tabs. The card can be dismissed manually by clicking the X button. It is automatically dismissed by adding a pin via a context menu or by dragging the tab over the card and pinning.	6014	97 %

	SidebarCollapsedWindows.sys.mjs	Process-wide owner of the per-window collapsed state for the sidebar Open Tabs panel. State is keyed by the SessionStore window id (`SessionStore.getWindowId`) and persisted to the `sidebar.openTabsPanel.collapsedWindows` pref as a JSON object whose keys are window ids and whose values are `true` for collapsed cards. Entries are dropped when a window closes or when a hydration sweep finds an entry whose window is no longer open. Private windows never write to the pref. Consumers add a listener for the `CollapsedWindowsChanged` event and call `requestUpdate()` (or equivalent) on every dispatch. The pref is the single source of truth.	5475	-
	SidebarManager.sys.mjs	SidebarManager is a singleton that handles startup tasks like telemetry, adding listeners and updating sidebar-related preferences.	13225	-
	SidebarState.sys.mjs	What each `sidebar.visibility` value means for the launcher. The values are orientation-exclusive, so a mode implies the tab orientation it belongs to. @typedef {object} VisibilityMode @property {"always" \| "user" \| "never"} launcherVisibility What governs whether the launcher shows: it always shows, it is the user's to show and hide with the toolbar button, or it never shows. This also says what the toolbar button does in this mode - toggle the launcher's expanded state, toggle the launcher, or toggle the panel. @property {boolean} expandable Whether the launcher has an expanded state at all. Only vertical tabs do. @property {boolean} [userVisibleOnEnter] Where the user's choice starts when this mode is entered. Only meaningful for modes whose launcher is the user's to control. @property {boolean} [expandedOnEnter] Whether the launcher is expanded when this mode is entered. @property {boolean} [userVisibleWhenUnknown] What restored state that says nothing about the launcher means. Left unset by the modes that would rather keep the launcher as the window has it.	30456	-
	SidebarTreeView.sys.mjs	Tree view node which can be focused via keyboard navigation. @typedef {object} TreeViewNode @property {"card-summary" \| "folder" \| "row" \| "separator" \| "empty-folder"} type @property {Element} [list] - The parent `<tab-list>`. @property {Element} [card] - The parent `<moz-card>`. @property {object} [item] - The object from `tabItems`. @property {number} [index] - The item's index within its list's `tabItems`. @property {Element} domNode - The rendered DOM element, or null if not rendered.	18113	-
