How to Start Private Browsing and New Tabs in Firefox Computer?

Learn how to open a Private window and New Tab window within the Mozilla Firefox computer. This helps in securing privacy and does not store data online.

Your safety online directly correlates with your protection physically. It is for this reason that online privacy should be taken seriously. How do you maintain online confidentiality when you are using a computer that is not yours, or you are in an internet cafe? One of the most effective ways is by browsing in incognito (or private) mode.

Incognito mode makes sure your browsing history is not saved, and therefore certain private data is secured. In this article, I will show you how to use private mode, and how to open new tabs in Mozilla Firefox.

Before we go any further, you might wonder what private mode is and what is unique about it. Let’s answer that first.

Incognito mode, also known as private browsing, is a privacy feature in some web browsers where the browser creates a temporary session that is isolated from the browser’s main session and user data.

When browsing using incognito mode, the browser doesn’t save:

  • the pages you visited,
  • your search bar entries,
  • listings of your downloads,
  • cookies and cached web content.

In this way, the data and session are secret and do not store anywhere on your computer. If you reopen the private browsing mode and visit the same website again, you will be considered as a new user. Perhaps, this is a more secure way of browsing the internet in this digital age.

I prefer using the incognito mode on Firefox whenever I have to use my mother’s laptop due to some unforeseen circumstances. It leaves behind no history or any other such information. Let’s see how to open the incognito tab in Mozilla Firefox.

You can now start browsing away with no fear of having a search history, download list, and other private information saved on the browser.

This will open the new Firefox private browsing window, however, if you’re interested to open the link in the Firefox private window, you can do that as well.

If you want to know whether you are using Incognito Mode on Mozilla Firefox or not, just check the window you are using for a purple mask at the top. If the purple cover exists, you are browsing in Private browsing mode.

Use Mozilla Firefox in Private Forever

Mozilla Firefox is set to remember history by default. You can technically browse in incognito mode forever if you change this setting in your Firefox Privacy Options.

Here are the steps to set Firefox private browsing mode always:

  1. Launch the Firefox browser on the computer.
  2. Click the horizontal 3bar icon menu button.
  3. Select Options.
  4. Choose the Privacy & Security panel.
  5. Scroll down up to the History section.
  6. Click on Use custom settings for history from the resulting drop-down menu.

  7. Select the Always use private browsing mode setting.

This will set the Firefox browser in private browsing forever. You can select Never remember history as well from the drop-down menu, and you will always be in Incognito mode. Once everything has been changed, close, and restart Firefox to effect the changes.

Having your browser set to always browse in incognito mode means you can’t view your download list, save any passwords from your frequently visited websites, and view your browser history, among others. I would recommend using the mode when you are dealing with sensitive information.

How to Open New Tabs in Mozilla Firefox?

I wouldn’t be exaggerating if I told you that opening a new tab in Mozilla Firefox is as simple as ABC.

  2. On your toolbar, select the plus add icon icon that appears after your last open web page to open a new tab.

    Can you elucidate if the 2nd Tab in a private window is also private from the 1st Tab? What about if I start a 2nd window, and then attach that window’s tab to the first window?

      Hi Terry, of course you can easily do that. Firefox does allow merging the tabs into single window. You can simply drag and drop the private tab into another private window. But, we can’t merge the private tab into normal tab.
