When will Firefox unblock Java

I understand that do to the security issues of Java 7 update 10 that Firefox blocked all Java usage, but since update 11 fixes these issues, when will Firefox unblock Java usage. I have already installed update 11 for java.

If your java is outdated then its disabled, enable your java plugin

Firefox Menu > Tools > Addons > Plugins

  • Enable Java plugin.

Check whether your java is upto date or not.

It says that my plugin is up to date: yet still won't work (ex. pocket-monkey,com & other sites), yet will work on others.

Java 7u11 is blocked because a cracker was caught selling a new 0-day vulnerability that nobody knows about yet. And there appear to be at least two other vulnerabilities in u11 as well that need fixing. If you still need to enable Java, this article will help you unblock it.

In the article it shows the plug in symbol in the address bar; I don't even see that when I try to enable Java. I really hope they fix all this soon!

FF "announced" that I needed to update/reset. I did so - it killed all (ALL) of my add-ons without telling me it was going to - very aggravating. FF 22 also killed all Java on all sites. I checked the add-ons under tools - according to that, it was enabled. Just in case, I reinstalled the latest Java - still nothing. Now I cannot view any pictures on any site at all, nothing but text.

To avoid confusion:

Make sure that you do not block JavaScript.


Clear the cache and the cookies from websites that cause problems.

"Clear the Cache":

  • Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
