Tab Scope is a lightweight Firefox add-on designed for Windows desktops that shows a quick preview of a tab’s content when you hover over it. Instead of switching tabs to check a page, you can glance at a thumbnail or snippet to confirm the site, headline or media before switching focus. This makes browsing more efficient when you have many open tabs or are juggling research and reference pages. Previews load instantly and are intended to help you scan tabs for relevant content without breaking your workflow. The add-on reduces tab-switching, improves navigation and helps you manage multiple pages side by side. It works well for multitasking—research, streaming queues, shopping and any session where fast context matters. The extension is designed to be resource-conscious and configurable. You can adjust hover delay, preview size and behavior through the add-on options, and it operates locally within your browser to protect browsing data. To install, visit the Firefox Add-ons site from your Windows PC, add the extension to Firefox and use the toolbar or contextual menu to access settings and permissions.



Wow, just wow! Tab Scope is everything I needed and more. The reminders keep me on track, and I feel so accomplished every time I tick something off. Like they say, a tidy mind is a tidy life!
