Firefox 17.0.1, xp, sp3 I got to tools>add-ons, check for updates. It shows both "Java(TM) Platform SE 7 U9" and "Java Deployment Toolkit 7.0.90.5" as out of date. I do the update part and download updates. But, when I recheck, Firefox tells me that these are still not updated.

I do the whole updates process. After I check again in the Add-on update checking, it still shows both of the above Java's as still being outdated. (What is going on here
