Clearing your internet/browser cache

The following is a step-by-step guide on how to clear your web browser's cahce, cookies, and history.


Clearing your web browser's cache, cookies, and history may remove some data that you wish to keep. For details, see About cache, cookies, and history below. For an alternate troubleshooting method, see Troubleshooting alternatives.


In most computer-based web browsers, to open menus used to clear your cache, cookies, and history, press Ctrl-Shift-Delete (Windows) or Command-Shift-Delete (Mac). If this doesn't work, follow the appropriate instructions below.

If you don't see instructions below for your specific version or browser, search your browser's Help Menu for "clear cache". If you're unsure what browser version you're using, from the Help menu or your browser's menu, select About [browser name]. In Internet Explorer and Firefox, if you don't see the menu bar, press Alt.

About cache, cookies, and history

Clearing your web browser's cache, cookies, and history may remove data such as the following:

  • Saved passwords
  • Address bar predictions (e.g. ChromeFirefox)
  • Shopping cart contents, etc.

While you should clear your web browser's cache, cookies, and history periodically in order to prevent or resolve performance problems, you may wish to record some of your saved information first. If you are unable to do so, see Troubleshooting alternatives below.
