I'm not sure about your first issue. I also can't get the audio to play, so I assume that the website is using a feature that's not compatible with Firefox.

However, your second issue is actually not an issue. Firefox simply doesn't support the WebSQL. WebSQL API was a concept that was dropped in late 2010 before it was actually introduced as a standard. Mozilla was hugely against the WebSQL API, instead backing the IndexedDB API, which became a standard.

In other words, that website's only going to work on Google Chrome, Safari or Opera because they were the only browsers that ever introduced support for the experimental feature before it was abandoned.

Hi s90r, at least those videos are easy to download. If the player is already up, you can use right-click > Save Video As. If you are looking at a link to the video, you can right-click the link and Save Link As.

Hello s90r,

Really weird problem .....

When audio didn't work in Firefox; I tried it in Edge, where it does work.

I noticed that it is the volume slider that is stuck in Firefox, and the only thing that would make any sense (to me) is the fact that since the last update one can no longer set Flash to "Always Activate" - the site in question would have to ask to enable/allow Flash, which in this case doesn't happen .....

"media.play-stand-alone" : changing it's value to "false" worked for me.
