Confusion on browser compatibilty

Oct 11, 2016

Excuse my ignorance here, but I need to understand what I'm dealing with in terms of browser playback on desktops.  I've read the page here:

. . . but still have questions.  This page states:

"If learners will be using mobile devices that support Flash, they'll see the default Flash version of your course, regardless of the mobile publishing options you select."

But what about desktop browsers?  If I select "include HTML5 output" when publishing, what happens on a browser like Firefox?  Your requirements state that Chrome is the only windows desktop browser for which HTML5 output is supported.   If Flash is always the default for desktops as well as mobile, how is is content ever displayed as HTML5 in Chrome? Is HTML5 only displayed if Flash is not installed on the user's computer?  

We have seen poor performance of our course in Firefox.  I looked at your requirements and just assumed this was because it was not supported (missing the part where it said HTML5). But if it's only HTML5 that is not supported in Firefox, how do we ensure that Firefox users ONLY see the Flash version?

Hi Lorin,

Chrome is the only desktop browser for PCs that'll support the HTML5 output, but Safari would also do so on the Mac. If you have Flash disabled in a browser, and you've included the HTML5 output you will still see that play - but certain browsers like Firefox just won't work as expected and that sounds like what you're seeing. Firefox is one of the browsers that has started blocking Flash by default, but it can be modified as shown here.
