Many thanks for flagging up this distinction, which I didn't realise. It seems I disabled JavaScript, and probably still have Java running! So I might be ignorant, after all, but due to confusion over JavaScript vs Java rather than anything Ruby mentioned. Is it easy to diable Java? Perhaps I should look back to the article I referred to.
Easy, but the method varies with browser :
For Seamonkey : Tools / Add-ons Manager / Plugins / Disable anything specific to Java
IE9 : Tools / Internet options / Security / Custom level / Scripting of Java applets / Disable
And don't you think it's also a good idea to have JavaScript disabled, even if it's completely different?
Not really : I run with JavaScript enabled in all my VMs (Productions, Secure, Sandbox, VPN, ...) as well as in the physical host, and disable it only when I need (e.g.,) right-click functionality that JS is deliberately over-riding (e.g., "Sorry, images cannot be saved" !) or when I cannot be sure that a pop-up is not malicious and need to be able to (a) stop it replicating, and (b) kill it.
It may be worth explaining to those who regard IT solely as a tool that Java (from Sun, via Oracle) and JavaScript (from Netscape, via ECMA and your favourite browser vendor) are two totally different beasts : the only thing they have in common is the first four letters, which were deliberately picked by Netscape when they wanted to re-brand their "LiveScript" technology. They picked the letters "J a v a" because, by then, Java was a cross-platform reality and they wanted to jump on Java's bandwagon.
JavaScript is an interpreted language that runs natively in your browser, and also in Adobe Acrobat; Java is a compiled language that requires a plug-in in order to run within a browser. Both run in so-called "Sandboxes", but JavaScript is inherently more secure.
