Firefox, like all programs tours have a private browsing mode with which you can surf the web without leaving any trace on your computer.
This function exists for both computers and mobiles. In fact, the private browsing mode does not hide your browsing activity from your ISP, but it ensures that, as far as device you, there is no trace she leaves behind.
For browsers that do not support multiple profiles, private browsing is quite useful. But if you do not like this, or because you are a parent and you want to know which websites your children are entering or because you are an employer and want to secure your company from inappropriate visits or for any other reason you can disable it in some browsers.
As far as Firefox and Windows is concerned, we will look at the current article, let's see what you need to do to disable the private browsing feature.
Work is done through the Windows Registry Editor and to continue from here on you will have administrator rights.
Step 1: Open the Windows registry. If you do not know how, press Win + R at the same time and in the popup window that appears, type Regedit and press the OK button.
Step 2: In the Registry Editor window that will appear, go to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox
It's possible that you don't have the Mozilla key under the Policies key. If this is the case, right-click the Policies key and select New > Key. Call it Mozilla. Next, right-click on the Mozilla key you just created, then select from menu environment this time, the Create > Key . Name this key Firefox.
Step 3: Now that you have the registry structured the way you need it, right-click the Firefox button and select Create> DWORD (32-bit) Value. Name the value DisablePrivateBrowsing and set its value to 1. Even if you are running Windows 65 bit you will choose 32-bit DWORD. If the DWORD value already exists, then just edit it and give it a value of 1.
That's it. Now in the Firefox menu the option "File> New Private Browser" no longer exists. If you regret it and want to restore Firefox as it was, simply delete what you did, or set the DWORD value to DisablePrivateBrowsing zero.
