Coincidentally or not, following a Moodle upgrade by my institution's administrator, mp3 files now open in a web player in a new tab instead of using the computer's own media player. Hotpot exercises containing wma files continue to open as before.
In addition, the css facelift add-on no longer applies.
My aim is for the students to view the Hotpot exercise and operate the audio simultaneously, which becomes difficult when the two are in different tabs. The same applies to mp4 files.
I believe we are still using Moodle 2.4.
Is there a means to prevent this happening (and to restore the css facelift) or have I missed the point of this new mode?
