I'll try installing a different media player such as VLC and see if this changes things...

If you can play via Chrome but not with Firefox, I suspect that the problem could reside in the Firefox configuration. I've tried Firefox in Windows with Adblock Plus enabled without any issue.

As in other browsers, you can specify how to open different file types e.g. like pdf files; you can opt for the imbedded viewer or use Adobe Acrobat's plugin.
Did you tried to change the default app in Menu/Options/Applications to open mp3 files? (e.g. I have installed VLC and use the VLC Web Plugin and it works fine).

Hope it helps.

No, I'm afraid not!

If you can't play a "download link", that probably means you don't have a MP3 player/codec installed in Windows.  I haven't done this in a while but my guess is that a standalone MP3 player will not fix it.  (Standalone = iTunes, WinAmp, VLC, etc).  What you need is something like the CCCP codec pack for Media Player Classic.

Apologies but I don't know what a proxy is.

And, I don't use any antivirus.

I am not asked, but eventually some more feedback can be useful.

With the browser SeaMonkey (2.33.1, 64-bit linux) I see player-buttons start/pause/stop under your debussy.mp3 link, when Adobe flash-plugin 11.2.202.457 is activated, and they work.

If I click on the debussy.mp3 URL directly, a pop-up-window asks me, if it should be opened with GNOME MPlayer, which works also.

With the same Seamonkey I get the red "Unable to read" message, when I try to klick the listen-demos on the homepage.

Thank you for your quick answer.

I do not see anything in your navigator report that can produce such issue.

Do you use a proxy, an ad-blocker, an antivirus ?

Thanks.

Do you have all audio codecs in green on this page : https://html5test.com/ ?

And what does the plugins section tell here : https://www.pianoteq.com/browser ?

No it does not play.

OK.
Can you go to this page http://jsfiddle.net/bznfsbhr/, and copy/paste us the text from the "Result" box.

Yes, I've tried Chrome and everything plays. But, I'm not a supporter of Google and would prefer to stick with Firefox.

I've gone to file/open file and tried to open an MP3 file from my computer and a play bar comes up, but, no other action whatsoever. When I click on the play icon, the counter does not proceed.

What should be my next step?

Are you able to play this directly under Firefox? : https://www.pianoteq.com/audio/d4/Debus...%20Ran.mp3

Did you try with another navigator (like Chrome) to see if is works better ?

Make sure, you can play mp3 files with your browser.
