To protect against potential Java vulnerabilities, Firefox asks you to activate Java for each website you visit that uses Java. If you trust the website, you can allow Java to run by clicking on the "Activate Java" message. If there is no visible area to activate Java content in the page, look for the plugin icon in the address bar, then click it and, in the message panel that opens, choose "Allow Now". For more information, see the How to allow Java on trusted sites article.

Hi,

Thank you for support. I can't find plugin icon in Facebook page address bar. Some website do show plugin icon.

I goto Open Menu, click Add-On, goto Plugins and set the Java(TM) Platform SE 8 U25 11.25.2.18 to Always Activate. But i can't set Always Activate for Java Deployment Toolkit 8.0.250.18 11.25.2.18, default Ask to Activate.

Than i close Firefox and open again. Still the same, can't upload photo in Firefox.

To protect against potential Java vulnerabilities, Firefox asks you to activate Java for each website you visit that uses Java. This should not affect your ability to upload photos to Facebook.

Are there any error messages being displayed or does Firefox just freeze or crash?
