How to clear browser cache, history and cookies?

Why is clearing browser cache necessary?

Browsers like Safari, Firefox or Chrome attempt to keep local copies of pages, images, and other content you’ve visited, so that it does not need to be downloaded again later.

Under certain circumstances caching does not work as intended and the browser insists on showing outdated content.

Depending on the browser caching problem, it might be necessary to bypass the cache or clearing it entirely.
