Incognito is enough only if you want to reduce the browsing history and session data saved by the browser on the device you’re using. It does not make you anonymous: websites and network operators such as your ISP, employer, or school may still observe activity. Choose a privacy measure based on who you want to keep information from.
What Incognito or Private Browsing saves—and what it doesn’t
Private browsing creates a separate browser session. It limits some records in the browser’s normal history, but it does not erase every trace from the device or conceal your traffic from websites and network operators.

Chrome Incognito
Chrome removes the session’s site data and record of visited sites after you close every Incognito window. Third-party cookies are blocked by default, although a site may behave differently if you temporarily allow them. Bookmarks you create and files you download remain on the device.

Firefox Private Browsing
Firefox does not add private-session history, form and search entries, download-list entries, cookies, or cached content to the normal saved browsing record. Temporary cookies are discarded when the last private window closes. Bookmarks, saved passwords, and downloaded files remain. Mozilla’s support page says Firefox version 151 adds an “End Clear Private Session” control; interface details can vary by version, so consult Mozilla Support for current instructions.

Who can still see activity in private mode?
Google’s guidance is direct: “While Incognito can help keep your browsing private on your device, it doesn’t make you invisible.” Websites you visit and organizations managing your network—including an ISP, employer, or school—may observe activity. Google services embedded on a site may also receive information about activity there. Mozilla makes the same distinction: Private Browsing does not make you anonymous, and sites, employers, and ISPs may gather information. Private mode changes what the browser retains locally; it does not make the connection anonymous.
Choose a measure for the privacy goal
| Your goal | Relevant measure | Important limitation |
|---|---|---|
| Keep history and session cookies out of the browser’s normal records on a shared device | Use Incognito or Private Browsing, then close every private window | Bookmarks and downloads remain; websites and network operators may still observe traffic. Google and Mozilla. |
| Reduce some cross-site tracking | Use browser tracking protection, such as Firefox Enhanced Tracking Protection | It can prevent hidden trackers from collecting data across multiple sites, but it is not a way to hide traffic from an ISP or employer. Mozilla Support. |
| Reduce what a local network or ISP can directly observe | Consider a VPN after evaluating the provider | The VPN provider becomes another party to trust and may be able to track browsing. A VPN is not equivalent to anonymity or comprehensive tracker blocking. Mozilla’s VPN explainer. |
| Use a separate browser designed to route traffic through multiple servers | Consider Tor Browser | It is a distinct tool, not a promise that every threat or tracking technique is defeated; cookies can still matter. Mozilla’s explainer. |
| Protect against malware or covert monitoring already on the device | Use device security and trusted-device practices | Private mode does not protect against malware, spyware, or keyloggers on the device. Mozilla Support. |
Is Incognito enough for your situation?
- On a shared computer: It can help keep a session out of the browser’s normal history and clear temporary session data when all private windows close. It does not remove downloaded files or bookmarks.
- From your ISP, employer, or school: No. Private mode does not prevent network operators from observing activity.
- From websites you visit: No. They may still observe activity, and private mode is not an anonymity guarantee.
- From trackers across sites: Private mode alone is not the same as tracking protection. Use a browser feature designed to limit trackers if that is your goal.
- From spyware or someone monitoring the device: No. Private mode is not device security.
Use private browsing without leaving obvious local traces
- Open a private window. In Chrome, choose New Incognito window; in Firefox, choose New Private Window. Labels and menus may differ by platform or browser version.
- Check what you save during the session. Downloads and bookmarks persist, even when other session records are cleared. Avoid saving anything you do not want left on that device.
- Close every private window when finished. Chrome ends the Incognito session after all Incognito windows close; Firefox discards temporary cookies when its last private window closes.
- Use a trusted device for sensitive activity. Private mode does not stop malware, spyware, or keyloggers already present on the computer.
Why “anonymous browsing” is an easy misunderstanding
Mozilla reports that a 2018 University of Chicago survey of 460 internet users found misconceptions about private browsing. The number describes the survey’s participants; it does not establish a percentage or show that private mode provides anonymity. The practical distinction remains: private mode can limit local browser records, while other parties may still observe online activity.
