hello, i don't think that flash needs java for downloading (maybe javascript - which is a different technology, but that will be enabled by default in firefox anyway unless you use an addon like noscript).

if you continue having issues installing it, try to obtain the flash offline installer directly from http://www.adobe.com/products/flashplayer/distribution3.html (choose windows, Plugin-based browsers)

Philip -- thank you. You are correct that it is JavaScript that is needed, not Java. When I go to the site you posted, it takes me back to the get.adobe.com/flashplayer/ site that tells me that JavaScript is currently disabled in my browser.

How do I enable JavaScript? I don't have any add-ons to disable it.

Thanks,

DEave

could you go to firefox > help > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on...

I see that Javascript is not enabled. How do I enable it?

i don't know why that setting was changed originally, but you can turn it back to the default like this: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named javascript.enabled. double-click it and change its value to true...
