What private browsing does and does not do
Private browsing stops your browser from storing a record of the websites you visit on your device. When you close a private window, your browser deletes the sites you went to, the searches you ran, and the passwords you entered during that session. Your internet service provider, your employer if you are on their network, and the websites themselves can still see what you are doing — private browsing only hides your activity from other people who use your device.
This matters if you share a computer or phone with family members, roommates, or colleagues. It does not protect you from data brokers collecting information about you online, and it does not hide your activity from your network administrator. If you are trying to remove your information from data broker sites, private browsing can prevent your own device from storing records of that work, but the data brokers themselves will still see your requests.
Private browsing is most useful as one part of a larger privacy routine — it keeps your household from seeing your searches, but it works best paired with other steps like clearing your cookies and using a password manager.
Key Takeaways
- Private browsing deletes your browsing history, cookies, and search history when you close the window, but only on your device.
- Your internet service provider and the websites you visit can still see your activity even in private mode.
- Each browser has its own name for private browsing: Chrome calls it Incognito, Firefox calls it Private Window, Safari calls it Private Browsing, and Edge calls it InPrivate.
- You can open a private window with a keyboard shortcut on any major browser, making it faster than using the menu.
- Private browsing does not protect you from data brokers or network monitoring, but it prevents other people who use your device from seeing your search history.
How to enable private browsing in Chrome
Open Chrome and press Ctrl + Shift + N on Windows or Linux, or Command + Shift + N on Mac. A new window will open with a spy icon in the top left corner and the words "You are now in Incognito mode." Everything you do in this window — every site you visit, every search you run, every form you fill out — will be deleted when you close it.
If you prefer using the menu instead of the keyboard shortcut, click the three vertical dots in the top right corner of Chrome, then select "New Incognito window" from the dropdown. The keyboard shortcut is faster if you open private windows often.
Chrome will remind you that your activity is still visible to websites, your internet service provider, and your employer if you are on a work network. This reminder is accurate — Incognito mode only hides your activity from other people using your device.
How to enable private browsing in Firefox
Open Firefox and press Ctrl + Shift + P on Windows or Linux, or Command + Shift + P on Mac. A new window will open with a purple mask icon and the label "Private Browsing." Firefox will not store any history, cookies, or search records from this window once you close it.
To use the menu instead, click the three horizontal lines in the top right corner, then select "New Private Window." You can also right-click any link and choose "Open Link in New Private Window" to open a specific page in private mode without opening a new window first.
Firefox offers a setting called "Always use private browsing" under Preferences > Privacy & Security if you want every window to be private by default. This is useful if you share your device and want to avoid accidentally storing history in a regular window.
How to enable private browsing in Safari
Open Safari and press Command + Shift + N on Mac. A new window will open with a dark address bar, indicating you are in Private Browsing mode. Safari will not save your history, cookies, or autofill information from this session.
If you use the menu instead, click "File" in the top menu bar, then select "New Private Window." You can also hold down the File menu and look for the Private Browsing option if the menu structure on your version of Safari is different.
Safari's private mode is particularly useful on shared family devices because it prevents Safari from suggesting websites you have visited when other family members start typing in the address bar.
How to enable private browsing in Microsoft Edge
Open Edge and press Ctrl + Shift + N on Windows, or Command + Shift + N on Mac. A new window will open with a blue mask icon labeled "InPrivate browsing." Edge will not store your history, cookies, or search terms from this window.
To use the menu, click the three horizontal dots in the top right corner and select "New InPrivate window." Edge also allows you to set InPrivate as your default browsing mode under Settings > Privacy, Search, and Services, though this is less common than in Firefox.
Edge's InPrivate mode includes an option to browse with tracking prevention set to "Strict," which blocks more trackers than the default setting. You can adjust this level in the address bar while in InPrivate mode.
What happens to your data in private browsing
When you close a private window, your browser deletes temporary files, cookies, and the list of sites you visited. Passwords you entered are not saved to your password manager. Bookmarks you create during private browsing are kept, because they are intentional actions you want to remember. Downloaded files stay on your device unless you manually delete them.
Your internet service provider sees every site you visit regardless of private mode, because the request has to travel through their network to reach the website. Your employer's network administrator can see the same thing if you are on a work network. The websites themselves log your visit and can track you using cookies, fingerprinting, and other methods even in private mode.
Private browsing is most effective when combined with other privacy practices: using a password manager so you do not have to type passwords into shared devices, clearing your cookies regularly, and being selective about which websites you trust with your information.
When private browsing is useful and when it is not
Private browsing works well for preventing household members from seeing your search history or the sites you visit. If you share a device with a partner, children, or roommates and want to keep some searches private, opening a private window takes five seconds and solves the problem. It is also useful when you are using someone else's device temporarily and do not want to leave traces of your activity.
Private browsing does not protect you from your internet service provider, your employer, or the websites you visit. It does not hide your location, your IP address, or your identity. If you need that level of protection, you would need a virtual private network (VPN), though a VPN is a separate tool with its own trade-offs and costs.
For the specific task of removing your information from data broker websites, private browsing prevents your own device from storing a record that you made those requests. The data brokers will still see your activity, but your household will not. This is useful if you want privacy from people in your home while you work on removing your information.
Frequently Asked Questions
Can websites see me if I use private browsing?
Yes. Websites see your visit, your IP address, and can track you using cookies and other methods even in private mode. Private browsing only hides your activity from other people using your device. If you want to hide your activity from websites, you need a VPN, which is a different tool.
Does private browsing protect me from data brokers?
No. Data brokers can see your requests and your activity the same way any website can. Private browsing only prevents other people on your device from seeing your browsing history. It does not stop data brokers from collecting information about you.
Will my passwords be saved if I use private browsing?
No. Passwords you type in private mode are not saved to your browser's password manager or autofill. If you need to log into accounts regularly, use a separate password manager app instead of relying on your browser to remember passwords.
Can my employer see my activity in private browsing?
Yes, if you are on a work network. Your employer's network administrator can see the websites you visit regardless of whether you use private mode. Private browsing only hides your activity from other people using the same device.
Do I need to turn off private browsing to read files?
No. Files you read in private mode stay on your device. Only your browsing history, cookies, and search records are deleted when you close the private window. You can read files normally in private browsing.
