How to Disable Incognito Mode in Chrome on the PC
You can disable Chrome's Incognito Mode completely on a Windows PC using a Registry addition. It sounds complicated, but it's fairly easy:
If you enter incognito mode and just want to get out of it and back to normal browsing, close the Incognito browser window. When you restart Chrome, it will open as usual in public browsing mode.
Select Start and type "CMD" into the search box.
Right-click Command Prompt and select Run as Administrator.
In the Command Prompt window, type REG ADD HKLM\SOFTWARE\Policies\Google\Chrome /v IncognitoModeAvailability /t REG_DWORD /d 1, then press Enter.
How to Disable Incognito Mode in Chrome on the Mac
On a Mac, the actions for disabling Incognito Mode in Chrome are slightly different, but the end result is the same. The biggest difference is in how Macs handle registry editing.
In the Finder, click Go > Utilities.
Open the Terminal app.
Type the following:defaults write com.google.chrome IncognitoModeAvailability -integer 1z
How to Disable Private Mode in Firefox on the PC

Select Private Begone in the search results. This add-on will completely disable Private Browsing in Firefox.
Select Add to Firefox.
If a pop-up appears called Add Private Begone, select Add.
To complete the installation, select Okay, Got It.
Close all instances of Firefox that are running, then restart Firefox. You should no longer be able to open Firefox in a private window.

Disabling InPrivate Browsing on Microsoft Edge requires a bit more attention to detail.

Name the new key "AllowInPrivate."
Double-click the DWORD called AllowInPrivate and make sure it is set to 0. If it's any other value, change it to 0.
Select OK. You can now close the Registry Editor.
Reboot your computer. Now when you use Microsoft Edge, the InPrivate option will no longer be available.
How to Disable Incognito Mode in Chrome on Android Phones
Unlike desktop computers, there is no built-in way to disable Chrome's Incognito mode for Android. There is, however, a third-party app you can install which does the same thing.
Start the Google Play app on your phone.
Search for Disable Incognito Mode and install the app when you see it.
Launch the Disable Incognito Mode app.
Tap Open Settings.
In the settings screen, turn on DisableIncognitoMode. Tap Allow to give the app permission when requested.
You can also return to the app and tap Hide icon after Setting to make the app disappear from the phone's app screen.

How Browsers & Operating Systems Treat Private Browsing
You can disable Chrome's Incognito mode on the PC, Mac, and Android, but not on the iPhone. Instead, on the iPhone, you can disable private browsing in Safari, since it's the default browser for iOS. As for Firefox and Microsoft Edge, you can disable their Private browsing modes on the PC, but not on the Mac, and since you need to use a plug-in for Firefox on the PC, be aware it's easily disabled by anyone who is somewhat tech-savvy.
If you're trying to control someone's browsing habits, you need to be aware of what browsers are installed on the devices and computers in use. There's no point in limiting Safari on the iPhone, for example, if Chrome or Firefox is also installed since you can't disable private browsing for those apps.
