Download flash player for 64 bit windows 7

Have a look at this:

If you are playing with the Firefox 4 beta (codenamed Tumucumaque), you likely already know this.. but will mention it anyway. Flash for [Internet] Explorer runs in Active X (one download) Flash for Firefox runs as a plug-in (a different download). You are downloading and installing the Firefox plug-in?

Based on what I have read and seen, there were only reported problems with flash in recent builds of Firefox 4 in Beta 7 on the Mac OS.

Umm...Internet Explorer, you mean Tina. Last time i checked Windows Explorer didn't need any Active X  

You are correct!.. my typo =)
