FF will not allow me to update Java nor Adobe on vista what do I do?

On a vista machine, I get Adobe update prompts in FF. I click on the Update adobe. An unsafe java message pops up asking if I want to up grade. I say yes, update tells me it updated, FF then goes to "check add on page" and just spins its wheels. this has been going on since FF decided to protect me about 2-3 days ago.
