It's dead, it's gone! It was a browser plugin and a security nightmare.
Adobe has now killed it and the browsers of today will no longer play flash animations, games or movies. It will not bother many of you and you will probably not notice.
I just wanted to warn you that if you visit a site still using Flash you will probably get a jigsaw piece icon with the message Click to enable Adobe Flash Player. This will no longer work. It is not a browser problem or a computer problem - it is just the way things now are.
If you really, really, really still want to play old Flash stuff read this.
I have a few bits and pieces that I saved over the years so I downloaded the SWF flashplayer and it works OK.
