Is your browser security blocking the course player?

Your browser's pop-up blocker might be preventing the course from playing correctly. First clear your browser cache (see below for instructions), then watch for these security messages:

Mozilla Firefox: A shield symbol appears in the address bar (top left). You must left-click on the shield, and disable protection on the page.

Google Chrome: A shield symbol appears in the address bar (top right). You must left-click on the shield, and allow the unsafe script to load.

How do I clear my browser's cache?

Google Chrome

In Google Chrome, clearing the cache is done via the Clear browsing data area in Settings. From there, check Cached images and files (as well as anything else you want to remove) and then tap or click the CLEAR BROWSING DATA button. 

Assuming you're using a keyboard, the quickest way to Clear browsing data is via the Ctrl+Shift+Del keyboard shortcut. 

Without a keyboard, tap or click the Menu button (the icon with three stacked dots) followed by More tools and finally Clear browsing data.

Tip: Choose the beginning of time from the Clear the following items from option at the top of the Clear browsing data window to make sure you get everything. 

In Chrome's mobile browser, go to Settings and then Privacy. From there, choose Clear Browsing Data. In this menu, check Cached Images and Files and press the Clear Browsing Data button once, and then again when asked.

Mozilla Firefox

In Mozilla's Firefox browser, you clear the cache from the Clear All History area in the browser's Options. Once there, check Cache and then tap or click Clear Now. 

The Ctrl+Shift+Del keyboard shortcut is probably the fastest way to open this tool. It's also available from Firefox's Menu button (the three-lined "hamburger" button) via Options, then Privacy, and finally the clear your recent history link.

Tip: Don't forget to choose Everything from the Time range to clear set of options, assuming that's the time frame you want to clear the cache over.

Microsoft Edge

In Microsoft's Edge browser, included in their newer versions of Windows, clearing the cache is done via the Clear browsing data menu. 

Once open, check Cached data and files and then tap or click Clear. 

The fastest way to the Clear browsing data menu is via the Ctrl+Shift+Del keyboard shortcut. 

Another option is via the More button (that little icon with three horizontal dots), followed by Settings and then the Choose what to clear button under the Clear browsing data heading. 

Tip: Tap or click Show more while in the Clear browsing data menu for additional items you can erase while clearing cached files and images.

Apple Safari

In Apple's Safari browser, clearing the cache is done via the Develop menu. Just tap or click Develop and then Empty Caches. 

With a keyboard, clearing the cache in Safari is super easy with the Option-Command-E shortcut.

Tip: If you don't see Develop on your Safari menu bar, enable it via Preferences, then Advanced, followed by selecting the Show Develop menu in menu bar option. 

Windows users can delete all of Safari's stored data through the menu button and then Preferences... > Privacy > Remove All Website Data.
