I am using Firefox browser with DuckDuckGo search engine. When trying to print a crossword puzzle daily form USA Today, I get the following message after pressing the play button: Application error: a client-side exception has occurred (see the browser console for more information). If I refresh the page, the site continues on and lets me print the puzzle. I tried switching back to Firefox for the search engine with the same result. This issue does not occur on Google Chrome, however. I have included a screenshot of website when error occurred. Thank you in advance.
