Adobe Flash is a nearly ubiquitous tool for displaying video on the web. You must install it, of course, but often that's not enough.
How to I turn on Flash Player? When I go to the download site for Adobe the banner says that I have flash installed. Then I go to a website that I know has flash and it says “This site requires that you have flash player.” I have already tried re-formatting to no help.
Wow. Reformatting sure seems like overkill for a problem like this. Reformatting’s a pretty major step, and not something I’d recommend without investigating things deeply.
I’m not sure what might be the problem in your specific case, but I can tell you this: there’s at least one excruciatingly simple reason that Flash might not show up on many web sites, even though you’ve installed it.

Click on the Tools menu, and then the Options menu item. Click on the Content tab and you should see something similar to this:
You can do roughly the same in Internet Explorer by adding sites to the “Trusted Sites” list, but the advantage of NoScript is simply ease of use. Literally a couple of clicks to add or remove a site from block list, and you’re on your way.
