Summary: Adobe Flash is a nearly ubiquitous tool for displaying video on the web. You must install if, 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. In a word: JavaScript. • What most sites don't tell you is that yes, you need Flash installed, but you also need JavaScript enabled. This might not be true for all sites, but it's certainly true for the vast majority using Flash that I visit. In my case, I run the FireFox extension "NoScript" which disables Javascript on all sites, except for those that I explicitly allow. So each time I visit a new site that uses Flash, I get the message "You must install Flash", when in fact all I need to do is tell NoScript to enable Javascript. Doing that the page and Flash video work just fine. In most cases, Javascript is enabled by default. But just in case, let's review how you turn on Javascript in IE7 and in FireFox. Enabling Javascript in IE7 On the Tools menu, click Internet Options, and then click on the Security tab. This dialog should result:
Click on Custom Level.... In the resulting dialog scroll down until you see Active Scripting:
Make sure that Active Scripting is set to Enable. Enabling Javascript in FireFox Click on the Tools menu, and then the Options menu item. Click on the Content tab and you should see something similar to this:
Make sure that Enable Javascript is checked. Risks? In my opinion, Javascript is not risky, unless you're regularly visiting risky or questionable sites, so I typically recommend people go ahead and run with it enabled. However, we've even recently seen a theoretical scary vulnerability in most routers that could be exploited via some malicious Javascript, so I might consider rethinking that stand. As I mentioned above, I recently started using NoScript, an extension for the FireFox browser which makes managing Javascript on a per-site basis a snap. Javascript is disabled on all sites except those you specifically allow. When you visit a site, you can quickly and easily add it to the allow list or return it to the block list with just a couple of clicks. 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. Related:

Posted by: - at July 30, 2007 12:17 PMI tried what you said, and had no luck. I was able to use flash n' everything before when I got my computer a few months ago. But recently it's like it dissapeared, and I tried installing it a billion times, and got nowhere. I heard about AVG affecting it, but i don't have AVG installed either. What do i do, it's driving me NUTS!

Posted by: ricardo at October 21, 2007 09:36 PMFinally, I found advice that really worked. It may have been a combination of steps. I (1) followed Leo's advice about enabling Java Script, then (2) used the download from this site: http://www.softwarepatch.com/internet/flash.html. After a reboot, a website that had been driving me nuts played just great. Thanks for having this advice!

Posted by: Steve Showalter at April 1, 2008 06:16 PMany ideas?
thanks Steve
This was very useful but did not help me. Flash used to work on my computer but has now stopped and won't download properly or work. Have you got any ideas as to how I could dowload Flash successfully again?

Posted by: Cat Moves at July 17, 2008 11:08 AMdoes not fit on my screen resolution. Can you code it so that it fit any size I choose to have on my monitor? Thank you.
For Mr. Showalter and others who've seen this without resolve, I happened upon yet another SIMPLE solution. Adobe recommends that you uninstall older versions of Flash Player, a tact I had not taken in previous upgrades. But, after the most recent upgrade wouldn't kick in, an uninstall and reinstall of the current version did the trick.
