If you're using an out-of-date version of the Adobe Flash Player plug-in, you may see the message “Blocked plug-in,” “Flash Security Alert,” or “Flash out-of-date” when attempting to view Flash content in Safari.
How to Update Adobe Flash Player Plugin in Google Chrome This updates the Adobe Flash Player plugin in the Chrome web browser, this is demonstrated in Mac OS but it works the same in Windows too. In the URL bar of Google Chrome, type the following address: chrome://components/ and hit return.
Clicking the indicator displays a message that Adobe Flash Player is out of date:
To continue viewing Flash content, update to a later version of Adobe Flash Player:
- Click the Download Flash button. Safari opens the Adobe Flash Player page on the Adobe website.
- Follow the instructions on the Adobe website to download and install the latest version of the plug-in.
If you need to use an older version of Flash Player, you can use Internet plug-in management in Safari to run the plug-in in unsafe mode for websites that you trust.
Contact Adobe if you need help downloading, installing, or using Adobe Flash Player.
It seems like the browser industry has declared war on the Adobe Flash Player and Flash is losing.

Is Flash Player Installed?
First, in Firefox, check to see if the Flash Player is actually installed. Type about:addons in the URL Address Bar. Check to see if Shockwave Flash or any Flash Player is installed. It might just take the simple act of activating it. Mine is currently set to, Ask to Activate, which means if you go to Facebook, instead of the video files automatically playing, you will have to click on them first. This used to work for YouTube, but no longer does.
On my system, Flash is installed, but it was not showing up in the list as being installed.
The solution is that you have to download and install the proper files by going to this Adobe Flash Player site.
Step 1 – Choose your operating system. In my case it is Windows 7.
Step 2, Select a version. That is the version of Flash you are trying to install. For Firefox you would want FP 28 for Firefox – NPAPI. Uncheck the optional offer in the center of the screen (unless you want it). Then click on the Yellow Download now button. Save it, but don’t install it yet.
Close your browser first and then run the installer. When finished, the Flash Player should be installed in Firefox. Go to Addons to check it out.

Choose How You Want To Activate It

Hopefully, this will solve your Flash Player issues in Firefox for now, but there is a time coming where Flash Player will not work at all. By then, we hope that all websites will have adapted and updated so it will not be a big issue.
Chrome Unblock Adobe Flash Player
This currently works on my Windows 7 computer with the latest version of Firefox 57.0.2 (64-bit).
