Web browsers are sophisticated, they make assumptions, they take matters into their own hands. You may think that each time you take a peek at a webpage you are seeing at it in its latest guise. Maybe you are not.
Traffic on the internet is phenomenal, but for the sophistication of browsers perhaps it would collapse under the strain.
So that it is not necessary to download all of this every time a site is visited browsers store some of these files in a cache on your computer.
This helps traffic. Unfortunately it also can mean that what you see is not the latest version of one or more of these files.
Browsers provide a refresh button, usually an open circle arrow ↻.
Google’s Chrome places it to the top left,
Apple’s Safari to the top centre,
as does Mozilla’s Firefox.
To see the most up to date version this is not always enough, still some files in a chain may be left behind.
If the refresh button fails then resort to deleting your history. Not as drastic as it sounds.
Google’s Chrome allows you to go straight to choosing specific types of cached data. At the top right, click the More ⋮ button, select More Tools, and then click Clear browsing data. Choose the types of data or files you want to remove from your PC, and then select Clear browsing data.
To delete your browsing history in Microsoft’s Internet Explorer 10 or 11, select the Tools ⚙ button, click on Safety, and then select Delete browsing history. Choose the types of data or files you want to remove from your PC, and then select Delete.
To delete your browsing history in Apple’s Safari, select History from the menu bar at the top of the screen, click on Clear History, choose from the periods offered and then select Clear History. I have to leave it to you to decide what period you want to delete.
To delete your browsing history in Mozilla’s Firefox, follow the same procedure as with Safari or select the Open Menu ☰ button, point to History, and then select Clear Recent History, choose from the periods offered and then select Clear Now. Again I have to leave it to you to decide what period you want to delete.
