> Java applets were removed from the browsers due to issues being found regularly
Java applets were killed off my MS's attempt at "embrace, extent, extinguish" by bundling an incompatible version of Java with IE, and Sun's legal response to this.
No, Microsoft has nothing to do with it. Browsers are controlled by Google and Mozilla and they decided to block Java plugin.
They never worked nice and always felt slow, unreliable and janky at the time. It’s easy to blame MS but no one was sad to see the back of them.
