Firefox blazed the trail for tabbed browsing. And it sure has made browsing so much streamlined (and fun!). Multiple windows sure are irritating. Along the line, Firefox tweaked its tabs (like having a close button for each tab). But one thing our friends over at Mozilla didn’t incorporate is tab thumbnails.

Good thing Firefox Showcase came along. It’s a Firefox add-on that shows tabs and windows as thumbnails under a single window, tab, or sidebar (take your pick). Pretty neat. It lets you get an overview of every window or tab that’s active.
