Apr 5, 2018 - If you are still having trouble installing Adobe Flash Player, try downloading the installer: Flash Player for Internet Explorer - ActiveX. Flash Player for Firefox - NPAPI. Flash Player for Opera and Chromium-based browsers - PPAPI. Some websites might use Adobe Flash Player to harm your computer. If you quit Chrome, your Flash settings won't be saved. The next time you open Chrome, you'll have to allow Flash again for any sites you added before. When you visit a page you trust that has Flash content, click Click to enable Adobe Flash Player.
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
Javascript (not to be confused with Java) is a computer programming language most commonly used to add dynamic functionality to web pages.
Web pages are written first in HTML, which is considered a mostly “static” descriptive language, meaning that HTML is most often used to describe the layout and other characteristics of how a web page should appear. Javascript (and dynamic HTML) adds the ability to define the behavior of a web page – things that the web page itself can actually do all by itself, without needing to communicate back to the web server (although it can if desired).
Javascript is considered a “scripting” language. While the term is somewhat vague, it generally means that Javascript is a programming language used to augment some other environment, such as the display of HTML-based web pages in your web browser.
Most common browsers come with the ability to run Javascript.
Examples of Javascript include most current web-based email clients, which allow you to browse and edit email without needing to reload the web page for every step of the process.

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

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.

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 scaryvulnerability
A vulnerability is a bug or design flaw in software that allows that software to be used in some malicious and unintended way.
All software has bugs, which are nothing more than mistakes made in the design or implementation of the software. Bugs can take many forms, from simply displaying something improperly, to crashing the application or entire machine.
When a bug can be intentionally triggered and in turn exploited for malicious purposes, that bug is termed a vulnerability.
The results of exploiting a vulnerability may have nothing to do with the software’s primary purpose. All that matters is that the vulnerability can somehow be used by malware – typically to infect the machine on which the software is running.

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.
The Adobe Flash Player browser plugin lets you view video and animated content in Firefox. This article has information about testing, installing, updating, uninstalling and troubleshooting the Adobe Flash plugin.

Flash plugin not working
If Adobe's Flash Player Help page does not show that Flash is working even though you have installed the latest version, your Flash plugin may be disabled in the Add-ons Manager. To make sure that Flash is enabled,
- Click the menu button , click Add-ons and select Plugins.
If Flash is disabled, select Ask to Activate in its drop-down menu.

Cannot view full screen Flash videos
See Flash videos won't play full screen.
Playing Flash videos makes Firefox hang
If Firefox stops responding or if the Flash plugin hangs or stops working when playing Flash videos or games, try these solutions:
- Pause or stop Flash in other tabs. You may need to close those tabs.
- Update Flash. See the Installing or updating Flash section above for instructions.
- Disable hardware acceleration in Flash settings. See Disable hardware acceleration in Flash for details.
- Update your graphics drivers. See Upgrade your graphics drivers to use hardware acceleration and WebGL.
- Disable Flash protected mode. See Adobe Flash protected mode in Firefox.
Other Flash problems and solutions
- Your Flash issue could be caused by an extension, theme, or hardware acceleration in Firefox. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems to narrow down the cause.
- Other solutions for general audio and video problems are listed in the Fix common audio and video issues article.
- If Flash content does not work, acts strangely, causes errors, or if you see a notice that you need to update Flash even after installing the latest Flash version, uninstall and reinstall Flash.
