when you try to print from a website click on the add on right before the address name and click on allow and remember.
Why was it blocked?
There are plugins which are being blocked by Firefox by default for a reason. https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist
Specifically the JDT plugin: https://addons.mozilla.org/en-US/firefox/blocked/p428
I seriously doubt the Java Deployment Toolkit plugin is needed for printing at all. Unless you have a specific need for Java, uninstall it.
