Blocks incognito tabs.

Incognito Blocker watches for new incognito tabs and closes them the instant they appear — no settings to fight with, no toggle to remember. Just a browser that stays out of incognito mode.

How it works

The moment a new tab opens in incognito mode, Incognito Blocker detects it and closes it automatically. It requires permission to run in incognito mode so it can see those tabs at all — that permission is the only thing it uses it for.

1

Detects instantly

A single Chrome event listener fires the moment a tab is created, before it ever gets a chance to load.

2

Closes automatically

If the new tab is incognito, it’s removed immediately — no prompts, no clicks, no way around it.

3

Stays out of the way

Regular browsing is completely untouched. Only incognito tabs are ever affected.

Open source and tiny on purpose

Incognito Blocker is open source, and this is the entirety of the code that runs. Nothing hidden, nothing to audit for hours — just one listener.

chrome.tabs.onCreated.addListener((tab) => {
  if (tab.incognito) {
    chrome.tabs.remove(tab.id);
  }
});

Setup takes 30 seconds

Chrome disables new extensions in incognito mode by default. Since Incognito Blocker’s entire job happens in incognito, there’s one extra step after install.

  1. Install the extension from the Chrome Web Store.
  2. Go to chrome://extensions and click Details on Incognito Blocker.
  3. Toggle on “Allow in Incognito.” That’s it — incognito tabs will close themselves from now on.

Built to see nothing

The extension’s permissions are only ever used to detect and close tabs — never to read, log, or send anywhere the pages you visit.
