On the one hand, there are still some very useful websites providing content using Java applets or Flash SWFs. On the other hand, activating the Java and Flash browser plugins pose a security risk, and, for example, re-configuring Java's whitelist each time you encounter a new trustful site is a hassle.
Therefore, I am looking for an isolated browser environment, which has only have to package Flash and Java. More functionality is not needed.
Note: I do not want to open possibly infected sited. For example, I usually encounter Java applets on old university sites, but do not wish to install the Java plugin in my main browser.
Does such a software exist?
Easy to use, there should not be any security prompts — I know what URI I paste into the address bar when I even open that isolated browser.
Up-to-date with respect to Java and Flash.
Reasonable price or free.
