I don't think it would be Java, as I don't have the java plug-in enabled. I have it installed, but I currently have them disabled.
I do agree that it is kind of dumb that it does not tell you WHICH plug-in is missing, or what it wants to install.
Sorry if I came across or implied that you are not smart to figure things out. That was not my intent at all. All I was trying to do was let you know what plug-ins I have enabled, and that the site in question (if it was youtube) does not present me with the dialog box to install a missing plug-in.
Well in your first post, to view the video here on DSLR you will need the Flash plug-in. No need to guess it's YouTube, which uses Flash or HTML5. If you play it on YouTube (click that link) with Firefox (latest versons) you don't need a plug-in. It plays without one using HTML5. -- Chris Living in Paradise!!
It's Flash. I have Java enabled for Fx 10 ESR but I have Flash disabled. That one doesn't play in HTML5 either. I don't usually need Flash at youtube as it will play in HTML5. But this one has to have Flash enabled. It does not want to download Flash because I already have Flash installed. It is telling me exactly what the problem is. I have Flash disabled in Fx Addons. -- When governments fear people, there is liberty. When the people fear the government, there is tyranny. Thomas Jefferson
The video was me being humorous, install the add-on to see what is in it, like the Bill.
Ahh! Now I see says the blind man to his deaf wife!
You posted two pics. The top one was showing that some site was asking you to "Install Missing Plugins" which were "Required to display all the media on this page".
I thought that the link, and the youtube video was the site you were on when you got the first picture.
But, that is not the case. You were adding that, as you said above, to be humorous, as the message you got on another site did not specify what "Missing Plugins" it needed. It could need Java, or Flash, or Silverlight, or Windows Media Player, or Quicktime, or whatever...your whole point was that it did not tell you. I'm guessing if you clicked the "Install Missing Plugings" button, you got whatever it needed, and you would probably have to go back and look to see what it added (and what other FUN things came with it).
Your whole point was this: Why is it not possible for that message to tell you what missing plugin(s) it needs, so you can go get them on your own, and install them.
