About

Cross-Domain Tab Guard is a lightweight Chrome extension that helps stop sites from opening unwanted tabs or windows to different domains.

It is not a general ad blocker and does not remove cookie banners, overlays, or page modals. It focuses on one specific annoyance: forced cross-domain new tabs and windows.

Features:
- Blocks cross-domain window.open() attempts
- Closes unexpected cross-domain tabs created by a page
- Normal mode allows links you explicitly click
- Strict mode blocks cross-domain new tabs more aggressively
- 5-minute pause
- Per-tab badge count
- Allowlist, export, and import
- Local storage only; blocked history stores domains, not full URLs
