Vertical Bookmark Bar от nuque

Vertical Bookmark Bar displays your existing Firefox bookmarks toolbar along the left or right edge of ordinary web pages. Keep frequently used bookmarks close while you browse, without creating a second bookmark collection.

• Show bookmark favicons and optional vertical labels.
• Browse the Bookmarks Toolbar and Other Bookmarks from compact flyout menus.
• Use familiar Ctrl/Cmd, Shift, and middle-click behaviour to open bookmarks.
• Organise bookmarks and folders from action menus or by dragging them.
• Choose the bar's side, width, colours, font, and auto-hide behaviour.
• Optionally reserve page space so the bar does not cover content.
• Keep the bar in sync with changes to Firefox bookmarks.

Bookmark information and display settings are processed locally on your device. The extension does not upload bookmarks, browsing data, or settings to external servers.
