Edge Last Tab

A small, permission-minimal Microsoft Edge extension for walking backward through recently viewed tabs.

Press the configured shortcut repeatedly to walk backward through recently viewed tabs in the current window. After reaching the oldest retained tab, the shortcut cycles back to the tab where you started.

The extension stores only numeric tab and window IDs in session storage. It has no access to page contents, URLs, titles, or browsing history.

1. Clone this repository:

   git clone https://github.com/maxbeizer/edge-last-tab.git

2. Open edge://extensions in Microsoft Edge.

3. Enable Developer mode.

4. Select Load unpacked.

5. Choose the cloned repository directory.

Open edge://extensions/shortcuts and assign any key combination Edge accepts.

The suggested shortcut for Go back through recently viewed tabs is:

• macOS: Control-T
• Other platforms: Control-Shift-L

The manifest uses MacCtrl+T so macOS receives the Control key rather than Command-T, Edge's New Tab shortcut. Chromium reserves some browser shortcuts and may reject or ignore those combinations.

After installing or restarting Edge, activate tabs normally to build the session history used by the command.

The extension uses Manifest V3 and has no build step or runtime dependencies. Validate a change with:

python3 -m json.tool manifest.json >/dev/null
node --check service-worker.js
node --test test.mjs
