Plug ins screen says I need to update Java, and when I do I'm told the install was stopped

more options

The Plug-Ins screen tells me I need to update Java. I click update and everything is fine until the install. I am told that 'the install failed because it was interrupted before it could be completed'. Java says that I am running the latest version, Version 7 update 51, but Firefox says I need to update. What gives?

Long story short, you do not need to update.

More info, please see: Firefox 28.0 is indicating that my installed Java SE 7 U51 is vulnerable (2014 03 20).
