I created this video to show how to use private browsing in Firefox, also known as Incognito Mode — perfect for browsing without saving history, logins, or cookies.
Private browsing in Firefox is one of those simple tools that becomes incredibly useful once you know when to use it. Whether you’re testing a website, logging into a second account, or just browsing without leaving a trail, this mode has you covered.
In the video, I walk through exactly how to launch a private window in Firefox:
- On desktop: Click the three-bar menu in the upper right, then choose “New Private Window”. Or just use the shortcut Ctrl + Shift + P on Windows or Command + Shift + P on Mac.
- On mobile: Tap the tab icon, then switch to Private tabs, and create a new one from there.
You’ll know you’re in private mode by the dark theme Firefox uses in these windows. From that moment, no browsing history, passwords, cookies, or form data will be saved once you close the window.
This doesn’t make you anonymous to websites or your ISP, but it does:
- Prevent autocomplete from storing your logins
- Let you view sites as a first-time visitor
- Help you bypass paywalls and location-based redirects (in some cases)
- Allow clean testing of logins, opt-ins, and forms
In the video, I also explain when I use private mode in my own work — like when I’m testing a new sales page funnel, viewing my YouTube channel as a non-subscriber, or checking cookie popups from a fresh perspective.
If you’re juggling multiple accounts, working with clients, or doing A/B testing, Firefox’s private window becomes an essential part of the toolkit.
Are you using private mode just for browsing, or have you started using it for professional testing too?
