I am about to start studying online & I apparently need java to be able to access ‘live’ tutorials. Firefox won’t allow the plug-in as it is ‘vulneralbe’. I know zero about all this. Please advise.

If you look in Firefox’s list of plugins there should be two Java plugins. The vulnerable one is theJava Deployment Toolkit. You don’t need this and it can be safely removed without affecting the Java Platform plugin which you do need to run web-based Java games & apps. I followed this guide to remove the Java Deployment Toolkit plugin from firefox:http://www.ghacks.net/2010/04/25/ho… Or you can just leave it as it is, disabled. One thing I should mention though. Next time you upate Java, that plugin will be injected in to Firefox again, and if it’s still suspect, Firefox will again disable it.So if you can’t abide it being there, save the above link for future reference. I wish Oracle would fix the vulnerability to save us all the time & trouble of removing it after every Java update. Or give us a “custom install” option so we don’t have to install it in the first place. message edited by phil22 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
