How do I clear my browser's cache (to improve its performance)?
Browsers temporarily store Internet files in a "cache" folder to enable you to quickly access websites you have recently visited. When this folder becomes full, your browser may become significantly slower or it may "crash." We recommend that you clear (or purge) the contents of the cache folder regularly.
