I highly recommend you to update your java version(if any).Also try going though the article:https://support.mozilla.org/en-US/kb/use-java-plugin-to-view-interactive-content. Hope it helps.

Basically I have two different scenarios as explained below -

Firefox version I have currently - 31.5 ESR and want to use for both scenarios

1) My application must use JRE 5 update 22. Can you please confirm if JRE 5 update 55 does not work with Firefox ESR 31.5 ?

2) My application must use JRE 8. Can you please confirm if JRE 8 update 45 work with Firefox ESR 31.5 ? As for JRE 8 update 45 it says VULNERABLE and does not allow me to enable, which version I should upgrade JRE to now?
