How to empty your web browser's cache

If you are using a browser, some website data is temporarily stored (cached) in the background. This allows the browser to partially use existing data from the cache and thus load the website faster. 

Depending on your settings, however, the cache can take up a considerable amount of memory on your computer over time. Furthermore, the browser often does not notice that the website’s content has been updated and instead loads the outdated files from the cache. Emptying the cache helps to eliminate these errors and causes web pages to load faster again, thus improving your computer’s performance.
