You know that whenever you visit a website, a great deal of data is collected about you by the company running the website, and by third parties that track you to serve ads. The more you use the web, the more information goes into profiles that companies like Google and Facebook use to target ads that match your search terms, the types of websites you visit, and more.
While you can use an ad blocker to not see ads, and also to block some of the trackers used to follow you around, these tools aren’t 100% effective. But there’s another way you can maintain your privacy: you can use private browsing. We look at how you can use private browsing in five popular web browsers: Safari, Chrome, Firefox, Edge, and Brave.
If you’re curious what the best web browsers are for privacy, read Safari, Chrome, Firefox: Which is the most private browser for Mac?
All the main web browsers offer a private browsing option. It was first available in Apple’s Safari in 2005, it’s also available in Firefox, and it is known by various names in other browsers: Google Chrome calls it Incognito; Opera calls it Private Tabs or Private Windows; Microsoft Edge calls it InPrivate Browsing; and Brave called it Forgetful Browsing.
When you use this feature, according to Apple:
When you use Private Browsing, Safari doesn’t remember the pages that you visit, your search history or your AutoFill information. Private Browsing also protects you from tracking by blocking known trackers from loading and by removing tracking used to identify individual users from URLs as you browse.
But Safari’s private browsing does much more:
And with locked private browsing in macOS Sonoma and later, Safari private browsing windows lock when your Mac goes to sleep or is locked. After waking the Mac, you need to authenticate to access private browsing windows, using Touch ID, or by entering your password.
In essence, private browsing lets you do what you normally do in a web browser—log into a site, get information, download items, etc.—but when you close the tab or window, you are forgotten. It’s especially good to use private browsing any time you use a public computer, or even a friend’s computer.
Note that as long as you’re working in a private browsing window, any website you visit will be able to access cookies and trackers that have recorded data since you opened that window or tab. As long as one private browsing window or tab remains open, the same private browsing session remains active, so think about closing these windows from time to time, or quitting your browser when you’re not using it to delete all this temporary data.
To open a new private browsing window in Apple’s Safari, choose File > New Private Window. The window looks like a regular window, but the address bar is dark.
To open a new tab in private browsing mode, press Command-T while viewing the private browsing window. Any tabs you open within a private browsing window will also be in private browsing mode.
You can also use private browsing in Safari on iOS. With Safari on an iPhone or iPad, you turn private browsing on or off. To do this, tap the new tab button at the bottom right of the Safari window (it’s the button with the two overlapping squares), then swipe to the right until you see the Private tab. Tap + to create a new private browsing window.
Doing this changes the color of the header and footer of the Safari window. As long as Private is activated, each new tab will be opened in private browsing mode.
To exit private browsing mode, tap the new tab button, then either swipe left to another tab, or top the close window button (the small x) at the top right of the private browsing window. If you stay on the Private tab, you can close one window and open another in private browsing mode by tapping +.
In Google Chrome, choose File > New Incognito Window to open a private browsing session. It’s a bit clearer that you’re using a private browsing window than with Safari; the title bar and tool bar are dark, not just the address/search field.
In Firefox, choose File > New Private Window. As with Chrome, the title bar and address bars are black, and there’s a little purple logo with the words Private Browsing at the top right of the window.
In Edge, choose File > New InPrivate Window. As with other browsers, Microsoft Edge makes the title bar and address bar dark, and has the InPrivate logo at the left of the title bar.
Brave has what is called “forgetful browsing,” which the company claims goes further than standard private browsing.
In Brave, choose File > New Private Window. Brave makes the title bar and address bar dark, and has a small pair of sunglasses at the right of the address bar, indicating that this is a private browsing window.
Private browsing is a great way to protect your privacy online. Some people use this all the time when they’re browsing, to minimize the amount of data collected by websites. Don’t forget to close all your private browsing windows when you’re done using them to completely clear out all the temporary browsing data.
