What an incognito tab does and doesn't do

An incognito tab (called "Private" in Safari, "InPrivate" in Edge) stops your browser from storing your browsing history, cookies, and temporary files from that session. When you close the tab, those records disappear. This is useful if you're shopping for a gift on a shared computer, checking your bank account on a public device, or simply don't want your household to see what sites you visited.

What incognito does not do matters just as much: it doesn't hide your activity from your internet service provider, your employer's network, or the websites you visit. Your IP address is still visible. If you log into your email or social media account in an incognito tab, those companies still know it's you. Incognito is about local privacy on your device, not anonymity online.

Key Takeaways

  • Incognito tabs prevent your browser from saving history, cookies, and cached files from that session on your device.
  • Opening an incognito tab takes one keystroke (Ctrl+Shift+N on Windows, Cmd+Shift+N on Mac in Chrome and Edge) or a right-click menu option.
  • Incognito does not hide your activity from your internet provider, employer network, or the websites themselves.
  • Closing an incognito tab erases the browsing data from that session, but data from previous regular tabs remains unchanged.

Opening incognito in Chrome

Press Ctrl+Shift+N on Windows or Cmd+Shift+N on Mac. A new window opens with a dark theme and an incognito icon (a spy hat) in the top left corner. You can also right-click the Chrome icon in your taskbar or dock, then select "New incognito window" from the menu.

If you're already in Chrome and want to open an incognito tab within an existing window, use the keyboard shortcut or click the three-dot menu in the top right, then select "New incognito window." Chrome will open a separate window rather than a tab, which is different from how some other browsers handle it.

Opening incognito in Firefox

Press Ctrl+Shift+P on Windows or Cmd+Shift+P on Mac. A new window opens with a purple mask icon in the top left. You can also click the menu button (three horizontal lines) in the top right, then select "New Private Window."

Firefox calls this mode "Private Browsing" rather than incognito, but it works the same way: your history, cookies, and site data from that window are deleted when you close it. Unlike Chrome, Firefox can open private tabs within the same window if you use the keyboard shortcut while a private window is already open.

Opening incognito in Safari

Click File in the menu bar, then select New Private Window. You can also press Cmd+Shift+N on Mac. The address bar will have a darker background to show you're in private mode. Safari does not have a keyboard shortcut for opening a private tab within an existing window — you must open a new private window each time.

Safari's private browsing mode works identically to Chrome and Firefox: it blocks cookies, clears history, and removes cached files when you close the window. If you're using iCloud Keychain, Safari will still offer to save passwords even in private mode, but those saved passwords won't be tied to your private browsing session.

Opening incognito in Edge

Press Ctrl+Shift+N on Windows or Cmd+Shift+N on Mac. A new window opens labeled "InPrivate" with a blue icon in the top left. You can also click the three-dot menu in the top right and select "New InPrivate window."

Edge's InPrivate mode functions the same as incognito in other browsers. When you close the window, your history, cookies, and cached data from that session are erased. If you use Edge's sync features across devices, those synced settings remain — only the local browsing data from that InPrivate session is cleared.

What happens when you close an incognito tab or window

Closing an incognito tab or window immediately deletes the browsing history, cookies, cached images and files, and autofill data from that session. If you downloaded a file during incognito browsing, the file itself remains on your computer — only the record that you downloaded it is removed from your browser.

Your regular browsing history and cookies from non-incognito tabs are completely unaffected. If you have multiple incognito windows open at the same time, closing one does not affect the others. Each incognito window or tab operates independently.

Common reasons people use incognito tabs

Shopping for gifts on a shared computer is the most straightforward use: you browse without the browser remembering the sites or showing targeted ads to other users of that device. Checking sensitive accounts (banking, email, medical portals) on a public or borrowed device is another — you avoid leaving login cookies behind that someone else could use.

Some people use incognito to prevent targeted advertising from following them across sites, though this only works locally on that device. Others use it to test how a website looks to someone who isn't logged in, or to bypass paywalls that limit free articles per month (though many sites now detect and block incognito browsing for this reason).

Frequently Asked Questions

Does incognito hide me from my internet provider?

No. Your internet provider can still see which websites you visit and how much data you use. Incognito only hides your activity from your browser and the device itself, not from your ISP or any network you're connected to.

Can websites tell I'm using incognito?

Yes, many can. Websites can detect incognito mode through technical methods like checking browser storage limits or API behavior. Some news sites and streaming services block access or show warnings when they detect incognito browsing.

If I log into my email in incognito, does that account stay logged in?

No. When you close the incognito tab or window, the login session ends and the cookie is deleted. The next time you open incognito, you'll need to log in again. Your actual email account is unaffected — this only clears the local session.

Can my employer see my incognito browsing on a work network?

Yes. Incognito doesn't hide your activity from your employer's network monitoring tools. If you're on a company network or using a company device, your employer can see which sites you visit regardless of whether you use incognito mode.

Does incognito stop websites from tracking me?

Partially. Incognito blocks cookies and local storage from being saved on your device, which stops some tracking. However, websites can still track you through your IP address, and some tracking methods work even in incognito mode. For stronger privacy, you'd need additional tools like a VPN or privacy-focused browser extensions.
