How to clear your browser's cache, history and cookies ?

clear browser cache

Why does it happen ?

To speed things up and conserve communications bandwidth, browsers like Safari, Firefox or Chrome attempt to keep local copies of pages, images, and other content you've visited, so that it need not be downloaded again later. Occasionally this  caching scheme goes awry (e.g. the browser insists on showing out-of-date content) making it necessary to bypass the cache, or clearing it entirely. ( source : wikipedia )

Depending on what is your browser cache problem, you might need to clear or bypass the cache.

Clearing the browser cache, history and cookies

In some circumstances, it may be worth clearing the entire cache (of your local browser). Below are some useful keyboard shortcuts to help you do it on any browser : Safari, Microsoft Edge, Internet Explorer, Google Chrome, Firefox, Opera, ...

  • In most Windows browsers the following keyboard shortcut will open the cache clearing settings : Ctrl ⇧ Shift Del
  • In Safari, use keyboard shortcut ⌥ Opt ⌘ Cmd E to instantly clear all caches

If you are using another browser or operating system, check the "Additional resources" chapter at the bottom of this page.

Bypassing the cache

When you encounter strange behavior, you can also try bypassing your cache. This will force your browser to re-download a web page's complete, up-to-date content. The rest of your cache is not affected.
