If you select private browsing mode, the browser won’t store your online activity.

All browsers have a ‘history’ tab that list all the online pages visited. Each browser has a different way to clear the online history.

Use your browser’s privacy mode


Chrome web browser logoIf you don’t want Google Chrome to remember your activity, you can browse the web privately in Incognito mode.

  1. On your computer, open Chrome.
  2. At the top right, click More  New Incognito Window.
  3. A new window appears. In the top corner, check for the Incognito icon .

You can also use a keyboard shortcut to open an Incognito window:

  • Windows, Linux, or Chrome OS: Press Ctrl + Shift + n.
  • Mac: Press ⌘ + Shift + n.

You can switch between Incognito windows and regular Chrome windows. You’ll only browse in private when you’re using an Incognito window.

  • Chrome won’t save your browsing history, cookies and site data, or information entered in forms.
  • Files you download and bookmarks you create will be kept.
  • Your activity isn’t hidden from websites you visit, your employer or school, or your internet service provider.



Firefox web browser logoPrivate Browsing automatically erases your browsing information, such as passwords, cookies and history, leaving no trace after you end the session. Firefox also has Content Blocking, which prevents hidden trackers from collecting your data across multiple sites and slowing down your browsing.

There are two ways to open a new Private Window:

Open a new Private Window from the Firefox menu

  • Click the menu button and then click New Private Window.

New Private Window in Firefox

The Private Browsing home page will open in a new window.

Open a link in a new Private Window

  • Right-click on any link and choose Open Link in New Private Window from the context menu.
Tip: Private Browsing windows have a purple mask at the top.

Microsoft Internet Explorer and Edge

Edge web browser logoMicrosoft Edge shares the same name for its private browsing mode as the old Internet Explorer: InPrivate browsing.

When you use InPrivate tabs or windows, your browsing data (like your history, temporary internet files, and cookies) isn’t saved on your PC once you’re done.

In Microsoft Edge, select the Settings and More  icon, and then New InPrivate window.

Safari web browser logoIn the Safari app on your Mac, choose File > New Private Window, or switch to a Safari window that’s already using Private Browsing. A window that’s using Private Browsing has a dark Smart Search field with white text.

When you use a Private Browsing window:

  • Browsing initiated in one tab is isolated from browsing initiated in another tab, so websites you visit can’t track your browsing across multiple sessions.
  • Web pages you visit and your AutoFill information aren’t saved.
  • Your open web pages aren’t stored in iCloud, so they aren’t shown when you view all your open tabs from other devices.
  • Your recent searches aren’t included in the results list when you use the Smart Search field.
  • Items you download aren’t included in the downloads list. (The items do remain on your computer.)
  • If you use Handoff, Private Browsing windows are not passed to your iOS devices or other Mac computers.
  • Changes to your cookies or other website data aren’t saved.
  • Plug-ins that support Private Browsing stop storing cookies and other tracking information.

Websites can’t modify information stored on your device, so services normally available at such sites may work differently until you turn off Private Browsing.

Note: None of the above applies in other Safari windows you may have open that don’t use Private Browsing.
