Clearing your Browser Cache and Cookies
Last modified 9/18/2023
What Is Browser Cache?
Your Internet web browser of choice (i.g., Internet Explorer, Firefox, Chrome or Safari, Edge, etc.) each use a cache or repository for stored data used to expedite the process of retrieving data and therefore loading web pages quicker. The cache can save web site data such as temporary files, cookies, history of visited web sites, download history, form data, passwords and other miscellaneous data.
Although the cache is meant to help speed up the process, from time to time it can also cause issues such as storing old passwords, or taking you to web sites that result in errors because they have recently changed. Routinely clearing the browser cache can alleviate some of these issues and is often the primary suggestion to fixing website errors.
Note:
Most computer-based web browsers can open a menu to clear the browser cache, cookies, and history by pressing the following keys on your keyboard Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac). If this method doesn't work, please follow the appropriate instructions below.
