BROWSER - How to Clear Browser Cache and History
Posted by David Lasecki on 28 July 2010 04:57 PM

Environment

Mozilla Firefox, Google Chrome, Internet Explorer


Purpose

The purpose of this article is to provide instructions on how to clear your browser cache and other data information across popular web browsers.


Problem

Over time, web browsers store data after each use. This data includes your browsing and download history. Web browsers use this information to speed up the loading of previously viewed pages by pulling this information from a specific directory located on your computer when a page is loaded. This helps webpages with lots of information or that host a large amount of media to load quickly.

However, with excessive use over long periods of time this temporary or "cached" data can accumulate and result in webpages loading incorrect/outdated information such as web links or login information. In addition, this excessive data can result in a slower web browsing experience since the browser needs to analyze and pull these pieces of data before displaying a web page. To help ensure the best browser experience, you should clear out your browser's data and cache on a regular basis.


How-to Guide

Delete your browsing data on:

Mozilla Firefox

  1. Click the Mozilla Firefox menu (icon with three horizontally stacked lines: New Fx Menu) on the browser toolbar.
  2. Click on History (icon shaped like a clock) from the drop-down menu that appears.
  3. In the History drop-down menu that opens, click Clear Recent History.... A dialogue will appear.
  4. In the Clear Recent History window, click on the down-arrow next to Details to select exactly what information you want to clear.
  5. In the Details field, make sure click the checkboxes for "Browsing & Download History", "Cookies", "Cache", and "Active Logins" are selected. You may leave the other checkboxes set to the default.
  6. Once the options in the Details field are selected, click the drop-down menu next to Time range to clear to choose how much of your history Firefox will clear. To ensure everything is cleared, select Everything.
  7. Finally, click the Clear Now button to complete the process.
