Java, a Web plug-in that was once ubiquitous but is dropping out of use in favor of HTML5, is still a valid security concern for Mac users.Chris explained why browser plug-ins are the worst security problems plaguing the Web today Web browsers have become much more secure and hardened against attack over the years.You can have it installed without actually using it, however, it’s possible to trick the applications into thinking legacy Java 6 is installed, without actually doing so. Disable SIP (System Integrity Protection) in OS X El Capitan. But Firefox → Tools → Add-ons shows Java 14.9.0 (and says it's outdated), though there is no option to de-install it.
The big browser security problem these days is browser plugins.
