Tab Anchor 作者： Sunny Katiyar

🔒 Tab Anchor
A browser extension that anchors a tab to its current URL — protecting it from accidental navigation, accidental closing, and unwanted title changes.

Inspired by the workspace tab-locking feature that Microsoft Edge included up to version 143.

Compatible with Chrome, Edge, and Firefox (109+).
