Mozilla Firefox is a popular web browser that is used by millions of people around the world. It’s a great choice for those who want to keep their privacy online. InPrivateBrowsingMode, or inPBM, lets you use Mozilla Firefox in a way that preserves your privacy while browsing the web. To start using inPBM, you first need to create an account on Mozilla Firefox’s website. Once you have an account, you can then sign in with it and click on the “inPrivateBrowsingMode” tab at the top of the window. This tab will show you all of the features that are available in inPBM. The first thing that you’ll need to do is set up your preferences for inPBM. You can do this by clicking on the “Preferences” button at the top of the window and then clicking on “Privacy.” In this section, you’ll need to set up how Mozilla Firefox treats your data when you’re using inPBM. You can also set up how Mozilla Firefox communicates with other websites when you’re using inPBM. Next, you’ll need to create a new profile for inPBM. To do this, click on the “Profile” button at the top of the window and then click on “New Profile.” In this new profile, name your profile “inPrivateBrowsingMode.” Once you’ve created your new profile, click on the “Create Profile” button at the bottom of the window and then enter your information into the fields below. In addition to setting up your preferences for privacy and communication within Mozilla Firefox, it’s important to make sure that you’re using correct security settings when using inPBM. You can do this by clicking on “Security” at the top of the window and then clicking on “Settings.” In this section, you’ll need to set up how Mozilla Firefox protects your data when using inPbm.


If you use Firefox and you don’t want it to keep track of every site you’ve visited, you can configure the browser to always use private browsing mode. Once you close all of your Firefox windows, none of your browsing history will be saved. Here’s how to enable it.

What is Private Browsing Mode?

Private browsing mode is a mode in Firefox that does not store your browsing history, download history, filled-out forms, searches, and other types of local data between browser sessions. (A browser session ends when you completely close all Firefox windows.) In fact, Firefox will not store your browsing history even within the browser session either, aside from a list of recently closed tabs that gets reset when you fully exit Firefox.

Private browsing mode is most useful when you share a computer with others, and you do not want them to see what websites you’ve been visiting. However, it does not prevent your browsing activity from being tracked in other ways—including by your ISP, through your router, and by websites that track your IP address.

How to Always Use Private Browsing Mode in Firefox

First, open Firefox. Click the hamburger icon in the upper-right corner of the window. (A hamburger icon looks like three horizontal lines sandwiched together.)

When a menu pops up, select “Options.”

On the Options page, switch to “Privacy & Security” settings by clicking on the padlock icon in the sidebar.

On the “Privacy & Security” page, scroll down until you find the “History” section. Click the drop-down menu beside “Firefox Will” and select “Use Custom Settings For History.”

With “Custom Settings” selected, look beneath the drop-down menu. Check the box beside “Always Use Private Browsing Mode.”

Upon clicking the checkbox, Firefox will ask to restart the browser. Click “Restart Firefox Now.”

Once Firefox restarts, private browsing mode will always be enabled.

To confirm this, return to Options > Privacy & Security > History. There should be a check mark in the box beside “Always Use Private Browsing Mode.”

Now you’re good to go. Just remember to close all of your browser windows when you are finished with your session.

If multiple people use your PC or Mac, it’s a good idea to set up a custom user account for each person, so that everyone’s browsing history will be managed separately. The instructions are different on a Windows 10 machine and on a Mac, but the results are the same: more privacy and less fighting over how the computer is configured.
