Can't use adobe flash, can't not use it.

Firefox has blocked Adobe Flash. FF says it is unsafe somehow; not specific. Says to update from version 18 something to version 19. Says that is faster and really good for gaming and all other things I never do. Nor do I need to surf at the speed of wind; that only confuses me. [further]
So I followed ff's command and tried to download adobe flash 19 from its own site, about 20 times. I do know how to download, and I followed all instructions to a t. Everytime I get to the point where the "run" window comes up, I get this message: "Adobe download manager has encountered a problem and needs to close." which it does. I have looked all thru the adobe site for a version better suited to my computer, but can't find anyplace where they tell you that. While I am running windows xp ser pac 3, I think my processor is too slow. However, we did fine with ver 18 until ff blocked it. So how can I find a program ff approves that will work with my computer, or what else do you suggest.
Thanks,

Hi Plodr.
As always, thanks for your help. But this time when I clicked on the link you sent, I got something called a '404 error' saying this url was not on the server.
