How to run with safety a Java certified web based applet

more options

I want to run with safety a Java certified web based applet. It's a Java game which it's certified. I have the latest Java version. I downloaded 52.9 ESR Firefox which there is a problem with it https://support.mozilla.org/en-US/questions/1235246#answer-1158505 , and I have noscript and https everywhere except from antivirus. Is it possible while playing, another script which does not belong to game to run?

Do you mean, will scripts in the page that surrounds the Java control be able to run? Probably, unless you have a very unique way to allow Java without allowing scripts.

I mean from the connection of my browser and game server. Is it possible? even with https and only allow the certified game? The applet is in the secure game site (https)

I don't have enough information to answer this.

Does the game use a plugin in Firefox, such as the Flash plugin? The Java plugin no longer runs in Firefox. When a game uses a plugin, it may have reach on your system that regular web content does not have.

What happens in the Java plugin is controlled by Java's security system, not Firefox's. I don't know the risk of external script reading or manipulating Java plugin content.
