How To Turn On Private Browsing In Firefox Permanently

Firefox’s address bar (or the awesome bar as it is called) is a useful feature because it remembers your bookmarks as well as the websites you visited earlier, and suggests them as you type your query.

All that sounds great unless the history contains private stuff, something which you don’t want others to see (you know what I mean :-) ). Imagine you are trying to help a family member find something on the net and that unwanted result pops up in the awesome bar. Not cool, right? Fortunately, there’s a private browsing mode in Firefox that lets you browse privately i.e without storing your browsing history.

This article will tell you how to quickly enable private browsing in Firefox. It’ll also show how to always start Firefox in private browsing mode (in case you don’t use Firefox as your default browser and only want it for private surfing).

Private Browsing

The private browsing feature in Firefox lets you browse websites without saving any information of your visited pages or sites. In other words it doesn’t save visited pages, forms and search bar entries, passwords, download entries and cookies.

How to turn on Private Browsing

Open your Firefox browser. Go to Tools –> Start Private Browsing. Or just press Ctrl+Shift+P on your keyboard.

A small window will pop up asking you to start private browsing. Click on “Start Private Browsing” button. All your current tabs will be available after you are done browsing privately.


Private browsing information screen will be available. Now Firefox will not record any browsing information.

    Some bad news: “Automatically start Firefox in private browsing session” is NOT the same as using a window with a purple mask at the top (which is presumably why a purple mask is not shown with this method). Only a purple mask can stop your entire family reading all your private emails because you closed a firefox window without logging out.
