TabSwitcher is a lightweight Chrome extension that lets you instantly switch between your last two active tabs using a keyboard shortcut (Shift+CMD+Space by default). It’s a productivity booster for developers, researchers, and multitaskers who constantly jump between tabs. Once you start using it, it becomes second nature.
