How to disable incognito browsing on your devices
You can block incognito mode in Chrome, Edge, and Firefox through settings on Windows and Mac computers, and through device policies on Chromebooks. The method depends on which browser you use and whether you want to prevent it on a single device or across multiple devices in a workplace or school setting.
On Windows and Mac, you disable incognito by changing browser settings directly. On Chromebooks, you use Google Admin Console or local device policies. Safari on Mac does not have a built-in way to disable Private Browsing through settings alone, though device management tools can restrict it.
Key Takeaways
- Chrome, Edge, and Firefox all have settings to turn off incognito mode, found in their preferences or policies sections.
- On Chromebooks, you control incognito through Google Admin Console if the device is managed, or through local policies if it is not.
- Disabling incognito in the browser itself prevents the feature from appearing in the menu, but does not prevent users from accessing it through command-line flags or extensions on personal devices.
- For schools and workplaces, device management tools like Intune (Windows), Jamf (Mac), or Google Admin Console (Chromebook) offer stronger enforcement than browser settings alone.
- Safari does not offer a native browser setting to disable Private Browsing; you must use device-level restrictions through Screen Time or Mobile Device Management.
Disable incognito in Google Chrome on Windows and Mac
Open Chrome and go to Settings (the three-line menu in the top right). Select Policies from the left sidebar — this option only appears if your device is managed by an organization. If you do not see Policies, your device is not enrolled in a managed environment, and you cannot disable incognito through Chrome settings alone.
If Policies is present, look for a policy called IncognitoModeAvailability or search for "incognito" in the search box. Set it to Disabled or Forced off (the exact wording varies by version). After you change this setting, close and reopen Chrome. The incognito option will no longer appear in the menu.
If your device is not managed by an organization, Chrome does not provide a built-in setting to disable incognito mode through the browser interface. In this case, you would need to use Windows Group Policy (on Windows Pro or Enterprise editions) or device management software to enforce the restriction at the operating system level.
Disable incognito in Microsoft Edge on Windows and Mac
Open Edge and go to Settings (the three-dot menu in the top right). Select Privacy, search, and services from the left sidebar. Scroll down to Clear browsing data and look for an option labeled InPrivate browsing or Allow InPrivate browsing. Toggle this setting to Off.
On managed devices, you can also enforce this through Edge policies. Go to Settings > Privacy, search, and services and scroll to the bottom. If your device is managed, you will see a section showing which policies are applied. Look for InPrivateMode and set it to Disabled.
If you are setting this up on a personal device that is not managed, toggling the setting in Privacy, search, and services is the only option available within Edge itself. On Windows 10 or 11 Pro, you can also use Group Policy Editor to enforce this at the system level, but this requires administrative access.
Disable incognito in Mozilla Firefox on Windows and Mac
Firefox does not have a straightforward toggle in the regular settings menu to disable private browsing. Instead, you must edit the configuration file directly or use a policy file if your device is managed by an organization.
On a personal device, open a new tab and type about:config in the address bar. Press Enter and click Accept the Risk and Continue. Search for browser.privatebrowsing.autostart. If this setting does not exist, right-click in the empty space and select New > Boolean. Name it browser.privatebrowsing.autostart and set the value to true. This forces Firefox to start in private mode but does not remove the private browsing option from the menu.
To fully remove private browsing from the menu on a managed device, your organization can deploy a policy file. This requires administrator access and is typically done through a management tool rather than through Firefox settings directly. For most personal users, Firefox does not offer a simple way to disable private browsing without using third-party tools or extensions.
Block incognito mode on Chromebooks
If the Chromebook is managed by a school or workplace, the administrator controls incognito through Google Admin Console. Go to Admin Console, select Devices > Chrome > Settings, and choose the organizational unit or group. Search for Incognito mode and set it to Disabled. The change applies to all Chromebooks in that group at the next sign-in.
If the Chromebook is not managed by an organization, you can restrict incognito mode through local device policies. Sign in as the device owner, press Ctrl + Alt + T to open the terminal, and type shell. Then enter the command to disable incognito (the exact syntax depends on your Chrome OS version). This method is technical and is typically used in schools or offices rather than on personal devices.
For personal Chromebooks without management enrollment, there is no straightforward setting in the regular Chrome OS interface to disable incognito. You would need to enroll the device in Google Admin Console or use a management tool to enforce the restriction.
Disable Private Browsing on Safari (Mac and iPad)
Safari does not have a built-in browser setting to turn off Private Browsing. Instead, you use Screen Time on Mac or iPad to restrict access to it. On Mac, go to System Settings > General > Parental Controls (or Screen Time depending on your macOS version). Enable Screen Time and set a Screen Time passcode. Then go to App Limits or Content & Privacy and look for an option to restrict Safari features.
On iPad, go to Settings > Screen Time > Content & Privacy Restrictions. Enable restrictions and set a passcode. Then go to Allowed Apps and toggle Safari off, or go to Safari and set Private Browsing to Off. This prevents users from opening new private tabs.
For organizations managing multiple Macs or iPads, use Apple Business Manager or a Mobile Device Management (MDM) solution like Jamf. These tools let you deploy restrictions across devices without requiring Screen Time setup on each one.
What happens when you disable incognito mode
When you disable incognito through browser settings, the private browsing option disappears from the menu. Users cannot open a new incognito window or tab through the normal interface. However, on personal devices that are not managed by an organization, a determined user can sometimes bypass this restriction using command-line flags, browser extensions, or by switching to a different browser entirely.
On managed devices (Chromebooks, Windows Pro with Group Policy, or Macs with MDM), the restriction is enforced at the system level, making it much harder to bypass. The browser cannot be configured to allow incognito mode even if a user tries to change settings manually.
Disabling incognito does not delete browsing history or change how the browser stores cookies and cache. It only removes the option to browse without recording that activity locally.
Frequently Asked Questions
Can I disable incognito mode on a personal device I own?
You can disable it in Chrome, Edge, and Firefox if your device is managed by an organization. On an unmanaged personal device, most browsers do not offer a simple setting to disable incognito. You would need to use operating system-level tools like Windows Group Policy (Pro or Enterprise editions) or device management software.
Will disabling incognito mode prevent all private browsing?
Disabling incognito through browser settings removes it from the menu, but on personal devices a technical user can sometimes bypass this using command-line flags or extensions. On managed devices, the restriction is enforced at the system level and is much harder to circumvent.
Does Safari have a way to disable Private Browsing?
Safari does not have a native browser setting to disable Private Browsing. You must use Screen Time on Mac or iPad, or deploy restrictions through Apple Business Manager or Mobile Device Management if you manage multiple devices.
How do I disable incognito on a work or school Chromebook?
If the Chromebook is managed, the administrator controls this through Google Admin Console under Devices > Chrome > Settings. Search for Incognito mode and set it to Disabled. The change takes effect at the next sign-in.
What is the difference between disabling incognito in the browser versus at the device level?
Browser-level settings remove incognito from the menu but may be bypassed on personal devices. Device-level restrictions (through Group Policy, MDM, or Admin Console) enforce the rule at the operating system level, making them much harder to work around.
