Clear cache & cookies. When you use a browser, like Chrome, it saves some information from websites in its cache and cookies. Clearing them fixes certain. Before we start, recall that browser history is a browser’s maintained list of sites that have been visited. Also, any one site may have its data, images, etc. Cached by the browser so that it can be reloaded faster. Clearing the entire cache, doesn’t necessarily clear the history of browsing. Chrome and Firefox make this distinction clear; Safari does not. Chrome Cache – Reference link: “” – Chrome version used: 51.0.x.x – Simplest steps. • Chrome > Clear Browsing Data • In the window that opens, select the popup for the desired time period. • Check just the box “Cached images and files.” • Click on “Clear browsing data.” II. Firefox Cache – Reference link: “” – Firefox version used: 47.0.x – Simplest steps. • Firefox > Preferences. • On the left sidebar, select Advanced. • In the horizontal tabs, select Network. • Under “Cached Web Content,” click on “Clear Now” III. Safari Cache Safari 9.x, by default, doesn’t make a clear distinction between clearing browsing history and clearing browser cache. Some sites that discuss clearing the Safari browser cache point to Apple’s page: “” This is a kitchen sink approach because, in order to clear the cache, you end up deleting your browser history and cookies as well. It’s not a bad idea for the novice, but it also may not be what you want. However, there is an explicit, somewhat hidden method for dealing with just the Safari browser cache. You can even do it on a page by page basis. – To Enable • Safari > Preferences. • Select the Advanced tab. • At the bottom, check the box: “Show Develop menu in menu bar.” A new Safari menu item will become visible called “Develop.” – To Clear All Browser Cache Develop > Empty Caches (CMD + OPTION + E) – Force Clear a Single Page’s Cache One of the virtues of this method, once enabled, is that one can force the clearing of the browser cache for a single page with SHIFT + reload. That is, hold down the shift key and click the reload button in the address/search bar. Feedback in the comments is welcome. John, Thanks for the tips. My routine in Safari for the last several iterations is quick and simple: COMMAND + OPTION + E empties the cache, and is signaled by Safari flashing the “Develop” in the menu bar. COMMAND + OPTION + R brings up a window that enables a host of options, including clearing the browser history, resetting top sites and removing website data. COMMAND + COMMA brings up the Safari Preferences window with further options as necessary. Simple and quick. Not sure of the viability of the above in El Capitan as I’m not there yet. When it comes to loading familiar websites, cookies and caches come in real handy. Cookies are files that are created on your computer by websites that you’ve been to. These files are stored in your cache and helps those pages load and run faster. However, it is important to clear your cookies and cache from time to time so that you can have the most updated versions of websites and forms. Keep in mind that after you’ve cleared your cookies, some pages may seem to load slower because all their images have to be loaded again. Additionally, website settings (like usernames and passwords) will be deleted, so be sure to have those stored in a safe place before clearing your cookies.
