Clear your web browser cache on a computer

A web browser's cache stores temporary instances of webpages, allowing them to load faster. This data is supposed to be recreated each time you visit a webpage, but sometimes things go wrong and the data gets corrupt. You can clear your cache (deleting the temporary files) to fix things like outdated pages and webpages freezing, not loading, or being unresponsive.
