How to clear your browser cache?

These days web browsers save all kinds of website data to your local system, this allows them to load the local copy rather than re-downloading data they already have, this is excellent for performance as the web page will load much quicker than if all of the data needed to be re-downloaded. In some cases it isn't helpful though. Currently, browsers cannot check to see if a resource was updated without downloading the entire resource, because of this they don't check and just use the local copy for a set amount of time before triggering a refresh. If updates are made to your website but you cannot see the changes then you can easily clear the cache.

Below are steps for some of the popular web browsers. Note: This can clear all of your browser data so any saved logins, remember me settings and browsing history will also be cleared.

Google Chrome:

  • Click the three dashes in the top right corner of the window
  • In the menu that shows click 'More tools'
  • In the second menu which shows click 'Clear browsing data'
  • This will show a new window, you can check or uncheck any options you would like to clear, however, make sure 'Caches images and files' is checked
  • Click 'Clear growing data'
  • If you return to the page which has been changed you should now see the changes


Mozilla Firefox

  • Navigate to the 'Firefox' button in the top left of the window
  • In the dropdown that shows click 'Options' then click 'Options' in the new menu that opens
  • In the options window which opens, click the 'Advanced' tab
  • Then click the 'Network tab'
  • There should be a section titles 'Cached Web Content' click the 'Clear Now' button to the right will clear the saved cache data on your machine
  • If you return to the page which has been changed, you should now see the changes


Internet Explorer 11

  • Click on the gear at the top right
  • This will open a new menu, click 'Safety' and then 'Delete browsing history'
  • This will then open a new window, ensure that 'Temporary Internet files and website files' is checked, you can check or uncheck any of the other options
  • Then click the 'Delete' button at the bottom of the dialog box
  • If you return to the page which has been changed, you should now see the changes

If the changes are still not showing, then the web server is caching the old data rather than the web browser.
The steps could vary depending on the operating system or version of the browser being used.
