I work for the state of Texas and the program I help administer hosts a website with an online training program for our stakeholders. Recently the training program files have been running poorly in the Firefox desktop browser -- the lessons don't play their audio, they run slowly, they freeze, etc. We have had several of our stakeholders complain to us about this issue. Since the training program is still running just fine in Internet Explorer and Google Chrome desktop browsers, we have been redirecting our stakeholders to complete the training program in either of those browsers. I talked to my program's website developer to see if they could resolve the issue at all, but they concluded that they cannot because the issue is incompatibility with the training program's file type. The website itself is functioning just fine; it is only the training program lessons that aren't functioning properly. The training program lessons were developed in Articulate Storyline: http://www.articulate.com/products/storyline-overview.php The best conclusion I can reach as to why the training program isn't functioning properly in Firefox is because a recent browser update is not compatible with Articulate Storyline software files. I request that this be investigated and fixed, as there does not seem to be any other solution to this issue other than to have Firefox address the problem. Our only other solution is to inform our stakeholders to not use Firefox for our website, which is not an ideal long-term solution.
