A trouble with Firefox or anything else!
Hi. Can anyone help me? What software(s) do i need for Duolingo's sound recording (!!!?) lessons? I have Firefox on my PC and I can't do this practices.
Duo uses Flash player. So it may very well be your problem. I think I remember the most recent browsers being able to execute Flash natively without the extension installed. You can try to fumble with your Flash extension in Firefox or try Chrome (or another one based on chromium like Opera).
