Of course, if you have a x64 bit system, its better to download a x64 bit Java version. However, i think Firefox won't be able to use it since Firefox isn't x64 bit (yet). So if you need Java in your browser, you'll need Java's 32bit version.

Keep in mind i could be wrong. It's just my guessing because i tried it out some months ago. I installed 64bit Java but Firefox couldn't handle it.

However in my opinion you won't recognize a difference between 32 and 64 bit, unless you play games in Java or do other resource intensive work. 32bit will always work on a 64bit PC, but not the other way around.

hello, you need to install the java plugin version that fits your webbrowser. firefox does only exist as a 32bit version at the moment (it will run on windows 7 64bit anyway) - so for java to work in firefox, you'd also have to install the 32bit plugin: http://java.com/download/windows_xpi.jsp

When it told me to udate java also i was wondering the same. Here is what i did. It worked no problem. Click on start click on control panel click on programs click on java icon. Now java box will be up. Click on top which says update. Then click on bottom update now. When its done. I was good to go. Firefox addons said up to date.

Thanks for that sigprn I have finally solved my problem updating Java I don't know what I'd do without people like you, I certainly wouldn't get anywhere close to solving it on my own.
