Most people find it rather uncomfortable once they understand how web browsers keep track of your online activity. But web browsers keep track of your past activity for a reason. That history comes in handy if you want to find a specific article again, or watch YouTube videos, or to log in to a website without having to fill in that login form each time.
But still, most people find this constant tracking a little on the creepy side. Not to mention that, if you share a computer with others, you might not want them finding out about a gift you secretly bought them, your interest in Ziggy Stardust, or your more private Google searches.
Fortunately, all of today’s web browsers make it very simple to erase your history and wipe away your online tracks. In this guide, you’ll find out about the information your browser automatically logs, what that data does—and how to get rid of it.
Just what is it that your browser saves?
Before you roll up your sleeves and start blitzing all the data stored in your browser, you should know what that information is and what it does. After all, on some occasions, you might want to clear specific types of files and not others. When you dive into a browser’s settings, you’ll see references to these different data types, though the terms might vary slightly from browser to browser.
First of all, our primary concern: your browser history, which is the list of sites and pages you’ve visited in the past. This history helps you retrace your steps, bring back pages you want to refer to again, and reach your favorite sites more quickly. Many browsers draw from your history to suggest specific URLs as soon as you start typing addresses in the search bar.
Browsers also track your download history, a list of files you’ve downloaded. Don’t confuse this history with the actual files themselves, which live somewhere on your computer’s disk. It’s simply a list of references to them, which can help when you’ve previously downloaded a file and now can’t find it, or you want to download the same file again.
Next up are cookies, little bits of code that sites will want to store on your system. Cookies help websites recognize who you are, but they come in all kinds of different forms. For example, if you go to a weather website and it instantly shows you the cities whose weather conditions you’ve previously looked up, that’s a cookie in action. If you return to a shopping site and it still has the same items in your basket, again that’s cookies at work. These files won’t harm to your computer, but some users don’t like being tracked in these ways, and prefer to delete them on a regular basis.
While you’re looking at cookies, you might see that your browser distinguishes standard cookies from third-party ones. Third-party cookies track behavior across multiple sites; they’re usually injected into ads rather than being part of the actual page code. You can blame this type of cookie for personalized ads: If you’ve spent some time searching multiple sites for tents, and then you start seeing tent ads everywhere, then third-party cookies are responsible.
Finally, browsers keep a “cache,” which contains local copies of graphics and other elements that your browser uses to load pages more quickly. If you head back to a site you’ve just visited, for example, the browser can draw site images from the cache rather than pulling them from the web again. The cache thus reduces the amount of data downloaded and speeds up the whole page-loading process. While it can provide snoops with a few hints about your browsing history, you need a certain amount of technical know-how—and luck—to understand it properly.
When you decide to erase your internet history, most browsers will list all these types of data separately. You can decide to clear everything out, which lets you start all over again as if you had a new browser on a new computer, or you might decide to keep certain types of files, like the cookies and cache, to make your browsing life more convenient.
Private or incognito mode
For those worrying about privacy, modern browsers allow you to surf in a mode called private or incognito. Simply open a window in private mode, browse as you please, and close it when you’re done. As soon as the window shuts, all the browsing history and stored cookies from that session automatically disappear. So, if you want to secretly shop for presents on a family computer, incognito mode is a good way to do it without leaving a trace.
However, this mode doesn’t erase everything you do. If you log on to a site like Facebook and Amazon in incognito mode, those pages will recognize you and record your browsing activity. In other words, your browser won’t remember what you’ve been up to, but any sites you log into will. This means you might see evidence of your private browsing in ads that appear later. And if you download files, private mode won’t wipe them either, though it will clear out your download history.
How to erase your history in any browser
No matter what browser you prefer, they all make it relatively easy to delete your history in a few minutes. And if you want to avoid the need to erase your past, you can simply take advantage of the browser’s private or incognito mode, so it won’t track your activity in the first place.
In Google Chrome:
Click the three dots to the right of the address bar to open the application menu, then choose Settings. Scroll down and click Advanced, then click Clear browsing data. Make your choices from the list, set the time period you’d like to clear, and then click the Clear browsing data button. Note: If you’ve set the browser to sync with other computers via your Google account, clearing your history will also erase data across all the other devices where you’ve signed into Chrome.
In Mozilla Firefox:
Click the three horizontal lines to the right of the address bar to open the Firefox menu, then pick Options. Click Privacy and then hit the link marked Clear your recent history. Switch to the Details tab to see different types of data, then set the time period via the drop-down menu at the top and click Clear Now to confirm.
In Internet Explorer:
You can clear your browsing history by clicking the cog icon in the top-right corner then choosing Internet options. On the subsequent dialog box, open the General tab and click Delete under Browsing history. Then pick your data types and click Delete to finish the operation.
Windows 10 users who are giving the new Microsoft Edge browser a whirl can also clear their browsing history. Click the three dots to the right of the address bar, then pick Settings from the menu that appears. Under the Clear browsing data heading, click Choose what to clear. Next, make your choices from the list, which includes browsing history and cached data, and then click Clear.
Finally, in Opera:
Click Menu in the top left of the screen. Then hit More tools and Clear browsing data to find the right dialog box. Choose your types of data, specify your time period, and click Clear browsing data.
