Home > How to Access Adobe Flash Content > Original Solution
These steps will hopefully enable Flash content on websites, even if the browser attempts to block it.
Note: Even as I write this, changes are happening, so what may work today may not work tomorrow. I will try to continue to update these instructions in the days and weeks ahead.
You first need to download a new program called Adobe Flash Player Debugger. This program not only will allow you to access Flash content (i.e. see it in your web browser) but it will also show you how to unblock Flash content from web browsers that are trying to block it. There are different debuggers for different browsers and different operating systems.
I have here three different sources of for the Adobe Flash Player Debugger files and other related files:
To save you some time, here is the link to download Adobe Flash Player Debugger for Chrome:
https://fpdownload.macromedia.com/pub/flashplayer/updaters/32/flashplayer_32_ppapi_debug.exe
And this is the link to download Adobe Flash Player Debugger for Firefox:
https://fpdownload.macromedia.com/pub/flashplayer/updaters/32/flashplayer_32_plugin_debug.exe
Close your Chrome (or Firefox) browser.
Install Adobe Flash Player Debugger.
In this step you will be creating and storing a file named mm.cfg. This file provides important settings for the Adobe Flash Player Debugger program.
For your reference, these instructions were taken from the Adobe website on how to Configure the the debugger version of Flash Player here:
https://helpx.adobe.com/flash-player/kb/configure-debugger-version-flash-player.html
This page is reproduced here.
Click on Windows Start, scroll down to Windows Accessories, and under that select Notepad.
Enter this text into Notepad:
ErrorReportEnable=1
TraceOutputFileEnable=1
PolicyFileLog=1
Click the File pull-down menu, and select Save As.
In the Save As window, navigate to either of these two locations, depending on whether you are using Chrome or Firefox:
C:\Users\pottsj\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash\System <--- for Chrome
C:\Windows\SysWOW64\Macromed\Flash <--- for Firefox
In the File name: box, enter mm.cfg (and remove any .txt at the end of the file name).
Click the Save button.
Open Chrome (or Firefox)
Flash Player will now automatically create this folder (if its not there already):
C:\Users\pottsj\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash\WritableRoot\Logs
Flash Player should now automatically create these files in that folder:
C:\Users\pottsj\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash\WritableRoot\Logs
It will create these two files:
flashlog.txt <-- will show Flash websites that were blocked by the websites (you will then add it to the mms.cfg file below)
policyfiles.txt <-- Flash Player records the successful flash sites you have visited
Test to see if Flash is working by going to a website with Flash. Here are some suggestions:
You will eventually find that a website that will not run Flash Player. In this step you will create a file called mms.cfg to override the block.
Mark Vejvoda has an online mms.cfg generator utility available here:
http://flash.vsoft.solutions/flash-eol-ee-config.php
To begin, navigate to the flashlog.txt file that Adobe Flash created back in Step 7.
Whenever Adobe Flash fails to run on a website, a record of that event is recorded automatically in the flashlog.txt.
To allow the Adobe Flash content to run, you will need to transfer the information from the flashlog.txt file to a new file called mms.cfg.
Where mms.cfg is located when using Chrome on Windows:
C:\Users\[username]\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash\System
Where mms.cfg is located when using Chrome on Mac:
/Users/[username]/Library/Application Support/Google/Chrome/Default/Pepper Data/Shockwave Flash/System
Stand-alone Flash applications mms.cfg file locations:
a. Windows
Assuming a default Windows installation, Flash Player looks for the mms.cfg file in the following system directories:
32-bit Windows - %WINDIR%\System32\Macromed\Flash
64-bit Windows - %WINDIR%\SysWow64\Macromed\Flash
b. MacOS
/Library/Application Support/Macromedia
c. Linux
/etc/adobe/ <--- Linux

The above methods may not continue to work, in which case other options might be available.
Harmon has announced it will offer support, but it's not clear exactly what that support will be

Portable versions of web browsers
Portable browsers are not usually susceptible to operating system updates because they are stored in non default locations
