Custom Tab Blocker

Block sites from opening new tabs, with one-click per-tab overrides and an optional hold-Ctrl bypass.

A Chrome extension that stops sites from spawning new browser tabs. Add a site to your block list and any tab it tries to open is closed automatically — with quick, per-tab overrides when you actually want a link to open. ## Features - 🚫 **Block new tabs per site** — listed sites can't spawn pop-ups or `target="_blank"` tabs. - 🌐 **Covers subdomains** — blocking `example.com` also blocks `news.example.com`. - 🎨 **Color-coded toolbar icon** — see each tab's state at a glance (green / red / orange / gray). - 👆 **One-click temporary override** — allow or block a single tab; it resets when the tab closes. - ⌨️ **Optional Ctrl-to-bypass** — hold Ctrl to let a link through, release to resume blocking. - ⚙️ **Inline options panel** — manage everything in a floating panel on the page, no extra tab. - 🔒 **Private by design** — no accounts, no network calls; your block list stays in your browser. You have two ways to add a site to the block list: - **Right-click the icon → "Block new tabs from this site"** — blocks the site you're currently on. Right-click again to choose "Remove blocking tabs for this site" to unblock it. - **Options panel** — type a domain (e.g. `example.com`) and click **Add**. You can paste a full URL like `https://www.example.com/page`; it's saved as `example.com`.
