Reddit Arrow Navigator by Flame

Reddit Arrow Navigator is a lightweight Firefox extension that brings true keyboard navigation to Reddit’s media viewer.

• Use ← and → to jump between images, videos, and galleries without touching your mouse.
• No Reddit API tokens or sign-in required — pure JavaScript injection.
• Autofinds the Next/Previous buttons even inside Reddit’s Shadow DOM.
• Works across all reddit.com pages and adapts as you scroll.

Perfect for power-users, accessibility workflows, or any time you want hands-free browsing.
