Web browsers such as Firefox and Internet Explorer try to save you browsing time by saving parts of the web pages you visit. By saving these files to what’s called the “cache” your browsing experience is sped up because certain features such as site navigation images don’t need to be loaded from the internet every time you visit a site.
Because of this time saving feature, you may not always see the most updated version of the website you are browsing. If you suspect that a site has been updated it but you are not seeing the updated version in your browser, simply use the browser’s refresh button to “reload” the site from what’s live on the site.
The pictures below show the location of the refresh button in Firefox and Internet Exporer 7. Note that the refresh button looks the same and is in the same location in Internet Explorer 8 as it is in Internet Explorer 8.
