One of our faculty members (thank you!) gave us a heads up about some issues that come up if you’re using Firefox 23 or IE 10 to work in Angel. Here’s a Penn State post about the issue:
Recent updates in Firefox 23 and Internet Explorer 10 now block mixed content by default, resulting in some content in ANGEL appearing as a broken link or not appearing at all. Many users do not notice this default setting change at the time of the update and this can result in possible confusion during their ANGEL experience. More information about this, along with a description for mixed content, can be found at https://wiki.mozilla.org/Security/Features/Mixed_Content_Blocker.
This issue is not specific to ANGEL and is browser-based. Currently, there are reports on the Mozilla bug tracking site (https://bugzilla.mozilla.org/buglist.cgi?quicksearch=mixed+content) for the New York Times, ESPN, and Flickr, just to name a few websites.
Internet Explorer 10 blocks non-secure content and is set to prompt a user by default. This option allows the user to permit that content providing that he/she knows and trusts the source. For details, see http://support.microsoft.com/kb/2625928.
As a work-around in ANGEL, instructors and instructional designers can edit “link” content item titles to include HTML, which will launch the links in a separate browser window outside of ANGEL. For more details and step-by-step instructions, see http://kb.its.psu.edu/cms/article/562.
Eugeniu and Brian over in CTLE did some troubleshooting (thank you!) and verified the PSU reports – here’s their summary and recommendation for Scranton faculty (emphasis mine):
We have verified that version 23 is indeed the problem. Firefox 23 provides no warning or prompt for the user to be able to open the mixed content. We have also verified that this effects links to external sites in ANGEL content items. However, these links work perfectly well in Google Chrome, IE versions prior to 10 and FF versions prior to 23.
This is not an ANGEL problem.

We will advise faculty who call here, for the time being, to use Google Chrome.
Please spread the word!
