Do you see the Java plugin in Tools > Add-ons > Plugins ?

Firefox is a 32 bit application, so you need to install the 32 bit Java version.

See Java Platform > Java SE 7U5 or Java 6U33 (Downoad JRE)

Thanks for answering. Yes, I see version SE 7 U5 10.5.1.255. I definitely have the 32-bit version installed.

Do you also see the Java plugin on the about:plugins page?

What do the test pages say?

• http://www.java.com/en/download/installed.jsp

Yes, I see the Java plugin out:plugins page. However, neither of the Java tests work.

Do the Java plugin link to the correct 32 bit Java version?

See:

You can see the installed plugins that are enabled on the about:plugins page.

You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of plugins on the about:plugins page. It is best not to leave that pref set to true as it exposes that full path
