how to get rid of history
November 25th, 2010

There are a hundred reasons you should want to get rid of your browsing history. I would guess that 99 of those reasons involve a visit to a site that most would rather not have their good name associated with publicly. I don't judge. It is also a problem for those of us who have Internet access at work and spend more time accessing the Internet than working. It should be said that there are other ways a system administrator can monitor Internet usage on a system-wide level, so getting rid of a browsing history might not really protect you. It's a good start, though.

This article is only a scratch on the surface of Internet tracking. Every computer, operating system, and software version makes the task slightly different. This article deals with the two biggest operating systems, and the current top five most popular web browsers. Things could change with newer versions, and an attempt will be made to keep this article up to date. Remember, you can always check the "Help" file of your Internet browser for more specific information.

How to Delete Internet Browser History

Clearing Internet Explorer history. First, follow this pathway: Tools > Internet Options > General > Browsing history. Click the "Delete" button and a pop-up window will appear with a bunch of options asking what you want to delete. You might want to uncheck the "Passwords" box unless you are 100 percent sure you know all of your passwords or have them written down somewhere. It's the curse of the autofill. Another option is to check the box at the top which preserves some information for sites which you visit often. Now press the "Delete" button in this window. If you go back to "General Settings" and look in the "Browsing history" area, you will see a "Settings" button. Click on that. At the bottom of the resulting pop-up, you have the option to choose the amount of time browsing history is saved (e.g. 2 days, 7 days, etc.).

Clearing Firefox history. First, follow this pathway: PC: Tools > Options > Privacy; Mac: Firefox > Preferences > Privacy. The pop-up window should read, "History Firefox will:" followed by pulldown menu with the following options: remember history, never remember history, use custom settings for history. I would suggest using a custom setting, as it allows you a lot more freedom. It also will bring you to a checkbox based menu where you can choose to have your history deleted after every use or keep it forever, amongst other things. To clear your history, go to: Tools > Clear Recent History. Select the appropriate checkboxes for your usage, and press "clear now." Please take note that this will delete all of your autofill passwords, too, so I hope you have them saved elsewhere.

Clearing Google Chrome history. First, follow this pathway: PC: Tool icon > Options > Under the hood; Mac: Chrome > Clear Browsing Data. The pop-up box will have a list of checkboxes for you to select. Decide what browsing information you would like to clear, check the appropriate box, and push the "Clear Browsing Data" button. Alternately, you can follow this path: History > show full history > edit items. This should open up a new tab with a list of your previously viewed sites. You can select which ones you would like to get rid of by checking the adjacent box, and then pressing the "Remove selected items" button. You could also just press the "Clear all browsing data..." button to get rid of everything.

Clearing Safari history. First, follow this pathway: History > Clear History... A pop-up will ask, "Are you sure you want to clear history?" Press the "Clear" button to finish the job. You should also change some settings in your preferences. Follow this pathway: Safari > Preferences > General > Remove History Items. Here you can choose an amount of time to keep your history around. Next, switch from the "General" preferences tab to the "Autofill" tab. Decide if you want form information for various sites to be filled in automatically or not. All I'm saying is that this could prevent some embarrassment.

Clearing Opera history. First, follow this pathway: PC: Menu > Settings > Delete private data > detailed options; Mac: Tools > Delete private data > Detailed options. The pop-up window will offer you a variety of checkbox options, all of which you should look over before pressing the "Delete" button. Remember that all autofill names and stored passwords will be deleted, so make sure you haven't forgotten them before deletion takes place. Now, follow this pathway: Opera > Preferences > Advanced > History. From here, choose whether or not to allow the browser to "Remember visited addresses for history and autocompletion." Choose "0" from the pulldown menu, uncheck the box underneath it, and press the "Clear" button.

Delete Search History

A handy design feature that browsers have is called AutoComplete or AutoFill. When you type a word, it guesses which word you are typing based upon previous form entries. This can be helpful, but it also runs the risk of telling everyone what you look for late at night or when you're supposed to be working. Thankfully, there is a way to clear that data, and prevent it from coming back.

Clearing AutoComplete Forms

  • Mozilla Firefox: Tools > Clear recent history > Everything > Check form and search history > Clear now
  • Google Chrome:
    • Mac: Chrome > Clear browsing data > Check "clear saved data"
    • PC: Tool icon > Tools > Clear browsing data
  • Safari: Safari > Clear cache
  • Internet Explorer: Safety > Delete Browsing History > History > Delete

Preventing AutoComplete Forms

  • Mozilla Firefox:
    • Mac: Firefox > Preferences > Privacy > Use custom settings > Uncheck "remember search and form history"
    • PC: Tools > Options > Privacy > Use custom settings > Uncheck "remember search and form history" You could also use Private Browsing under Tools > Start private browsing
  • Google Chrome:
    • Mac: Chrome > Preferences > Personal stuff > Autofill preferences
    • PC: Tool icon > Options > Personal stuff > Autofill options
    • You can also use Incognito mode by going to the Tool icon (File on Mac) > New incognito window
  • Safari: Safari > Preferences > Autofill > Other forms
    • You can also use Private Browsing by going to Safari > Private browsing
  • Internet Explorer: Tools > Internet Options > Content > AutoComplete Settings
    • You can also use InPrivate Browsing by selecting Tools > InPrivate browsing

Delete Cookies

Cookies are little pieces of text that websites use to tailor your browsing experience, and to keep track of your previous preferences and viewing habits. They might also contain saved shopping carts or be used to authenticate a user to a website. For the most part, they are used for good, all without you knowing the difference. However, they can be used by someone who wants to see where you've been. So, if you are trying to remove evidence of a website visit, it would be an especially good idea to delete the cookies, too.

Hard drive cleaners. There is a whole market of software designed to clean a hard drive. I can't personally recommend any of them, because I never have and never would use them. Firstly, I have nothing to hide. Secondly, I am nervous about them, and you should be, too. Free software versions of this type of drive cleaner are very often a vehicle for delivering a virus into your computer. Do a search and you will find a bunch of them. If you must, choose wisely, or check in with a knowledgeable source before installing.

Formatting. This doesn't so much erase the data as it simply makes the hard drive forget where it put everything. When your system is reinstalled, it will eventually rewrite over the top of the old information. A computer forensic specialist with the proper tools and knowledge could probably make short work of retrieving the information, but if you're doing something that would attract their attention, you probably deserve to be caught.

Thermite fire. Some people claim that the only way to ensure that data is irretrievable from a hard drive is to burn it. More precisely, you should heat it to the point of changing the properties of the metal that is used. You could do this in a forge or with a blow torch, but a more dramatic method would be to use a thermite reaction. Thermite is a combination of a metal powder and a metal oxide that, when burned, can reach temperatures in the 3,000°C range. Good luck finding it! Oh, and stand back, if you do.
