Adobe Flash Player Removal Information Page

(labeled Shockwave Flash in Internet ExplorerFirefox, and Google Chrome)


Adobe Flash Player (labeled Shockwave Flash in Internet ExplorerFirefox, and Google Chrome)[5] is deprecated computer software for using content created on the Adobe Flash platform, including viewing multimedia contents, executing rich Internet applications, and streaming audio and video. Flash Player can run from a web browser as a browser plug-in or on supported mobile devices. Flash Player was created by Macromedia and has been developed and distributed by Adobe Systems since Adobe acquired Macromedia in 2005. Flash Player is distributed as freeware.

Flash Player runs SWF files that can be created by Adobe Flash ProfessionalAdobe Flash Builder or by third party tools such as FlashDevelop. Flash Player supports vector graphics3D graphics, embedded audio, video and raster graphics, and a scripting language called ActionScript. ActionScript is based on ECMAScript (similar to JavaScript) and supports object-oriented code. Flash Player is distributed free of charge and its plug-in versions are available for every major web browser and operating system. Google ChromeInternet Explorer 11, in Windows 8 and later, and Microsoft Edge come bundled with a sandboxed Adobe Flash plug-in.[6][7][8][9][10]

Flash Player once had a large user base, and was a common format for web games, animations, and graphical user interface (GUI) elements embedded in web pages. Adobe stated in 2013 that more than 400 million out of over 1 billion connected desktops update to the new version of Flash Player within six weeks of release.[11] However, Flash Player has become increasingly criticized for its performance, consumption of battery on mobile devices, the number of security vulnerabilities that had been discovered in the software, and its closed platform nature. Apple co-founder Steve Jobs was highly critical of Flash Player, having published an open letter detailing Apple's reasoning for not supporting Flash on its iOS device family. Its usage has also waned because of modern web standards that allow some of Flash's use cases to be fulfilled without third-party plugins.[12][13][14]

In July 2017, Adobe announced[15] that it will end support for Flash Player on December 31, 2020, and continued to encourage the use of open HTML5 standards in place of Flash.[16][17] The announcement was coordinated with Apple,[18] Facebook,[19] Google,[20] Microsoft,[21] and Mozilla.[22] All major web browsers plan to officially remove Adobe Flash Player on December 31, 2020, and Microsoft will be removing it from the Windows OS entirely in January 2021 via Windows Update.[23] In October 2020, Microsoft released a preview for the Windows 10 and 8.1 update which removes Adobe Flash component from IE (named KB4577586).[24] Apple’s latest MacOS, Big Sur, which was released November 12, 2020, removed software compatibility for Adobe Flash Player. Starting January 12, 2021, content will be blocked from running on Flash.[25]

Alternatives for customers who want to continue to use the Flash-based BMC products

HARMAN International Packaged Browser solution

HARMAN International has an exclusive agreement with Adobe to provide extended licensing and support agreements for the enterprise Adobe Flash Player until the end of 2023. For details, go to https://services.harman.com/partners/adobe  .

BMC Software provides Limited Support for Adobe Flash-based capabilities in BMC products when used in combination with the HARMAN Packaged Browser application—Electron/Chromium version. Limited Support is provided temporarily until Dec 31, 2021, to cover the time period until customers upgrade to the latest BMC product version that has replaced the Flash-based capabilities.

Adobe Enterprise Enablement for legacy browser versions


The ability to run Adobe Flash Player depends upon the browser vendor's support. Running BMC Software products with outdated browser versions requires you to turn off automatic updates. This approach should be carefully considered and should be in alignment with your company's security group recommendations.

With Adobe Flash Player 32.0 Enterprise Enablement, companies can allow Flash Player content to be loaded from a set of trusted URLs by performing these actions:

1.    To allow Flash to run for a BMC product, in a mms.cfg file, enable the AllowListURLPattern option and add the list of trusted URLs as follows:

Example AllowListPattern configuration






For details about the AllowListUrlPattern options, the location of the mms.cfg file for different platforms, and other recommendations from Adobe, see the Adobe Flash Player 32.0 Administration Guide  .

2.    Push the mms.cfg file to all browsers that need to continue to use Flash.

3.    Prevent automatic updates of newer browser versions that will not allow Flash Player to load.

BMC Software has validated the Flash Player will continue to run with Flash Player Enterprise Enablement on these browser versions:

According to the announced information, for working environments there should not be an impact before January 12th.

  1. HARMAN can help you with a supported enterprise distribution of Flash Player as “Packaged Browser” solution
  2. If you have got Flash already installed on your machines, it might be sufficient to block updates for one specific browser such as Chrome, Chromium-based browsers (like e.g. the new Microsoft Edge) or Firefox (ESR) and apply an mms.cfg as in the example above
  3. If you are using Microsoft Internet Explorer or Edge Legacy mode, make sure to not install or block the Windows updates containing the removal of Flash as well as Flash integration components on the clients where you need to continue running flash. Also you might require to add the mms.cfg as above

If you have got a working environment, it might be beneficial to save a backup/snapshot of it – in case you need to restore due to a failure or by error installed an update removing functionality.

First of all: you should not do this. Flash is end-of-life and for that reason removed from the browsers. There have been many security issues with Flash, and it is just a matter of time for new issues will be found and exploited… and Adobe will not fix them anymore. So, best is to get rid of Flash and replace that for a product using UI code that is supported, like for instance HTML5.

If you still want to do this – at your own risk – you can take the following steps…

Preparation of the PC used for browsing

The browser used on your PC should somehow be prevented from upgrading (which is a security risk by itself). Newer versions of the browsers will remove Flash capabilities. Note that the PC software itself (Windows, OS X) might remove Adobe Flash too… Preferably, the PC is blocked from accessing the internet, although that will not remove the security risk completely.


Option 1 - Internet Explorer 11

Microsoft has announced the end of support of Adobe Flash Player and will start in January 2021 to disable Flash Player by default and block versions older than June 2020.

To use Internet Explorer:

·         For Windows 10 / Windows 8 make sure to update the system via Windows Update, so a current version of the Flash Player add-on is installed (version >= Enable the Adobe Flash add-on in Internet Explorer (if it is not enabled yet):

·         Open the Tools menu and select Manage add-ons

·         In the Manage add-ons window right click the Shockwave Flash Object entry and click Enable. (if you cannot see the entry switch to All add-ons in the Show selector)

Add-ons screen

·         Place the Flash Player configuration file (mms.cfg) on the system as described in Configuring the Flash Player.

Option 2 - Firefox ESR Portable

Firefox ESR Portable is a 'distribution package' of Firefox, which is not directly installed on the client's operating system. Instead, ESR Portable runs from any folder. For this:

·         Download Mozilla Firefox ESR Portable. Use version 78.6.0 ESR. The readme for this ESR release is here.

·         Run the downloaded executable to extract the folder structure.

·         Create a configuration file named FirefoxPortable.ini with the following content:


·         Place FirefoxPortable.ini extracted folder that contains FirefoxPortable.exe. This configuration file forces Firefox Portable always to invoke the 32bit version of Firefox.

·         Create the folder <Firefox ESR Portable Install Dir>\Data\plugins

·         Copy all files from %WINDIR%\SysWOW64\Macromed\Flash to <Firefox ESR Portable Install Dir>\Data\plugins folder

·         Disable auto-update for the Firefox ESR package and limit browser access to selected URLs:

·         Create a directory named distribution under <Firefox ESR Portable Install Dir>\App\Firefox

·         Create the file policies.json in the distribution directory and add the following content:

"policies": {
"DisableAppUpdate": true,
"DisableSystemAddonUpdate": true,
"CaptivePortal": false,
"WebsiteFilter": {
"Block": [
"Exceptions": [
"<app URL>/*"


·         Replace <App URL> with the URL of the software you need to run.
For example: "https://www.example.com/*".

·         Add other URLs in the same way if needed.
For example: ["https://www.example.com/*","https://www-dev.example.com/*"]

·         More details on the URL patterns can be found here.

·         Open Mozilla Firefox by running FirefoxPortable.exe and apply configurations specific to your target environment (e.g. import trusted certificates, set proxy, ...), then close the browser.

·         Zip the Firefox ESR Portable directory structure and transfer it to your client system.

·         Unzip it on the target system (in a folder of your liking).

·         Place the Flash Player configuration file (mms.cfg) on the system described in the Configuring the Flash Player section.

·         Start using the Firefox Portable browser by running the FirefoxPortable.exe executable.

Configuring the Flash Player

Starting with Flash Player's June 2020 release, configuration options were added to limit which content can be loaded by the Flash Player and options to configure update and removal of the plugin. Since January 12, Adobe Flash Player will only work with URLs that are explicitly listed in its configuration file.

To enable the Flash Player for your web applications, apply the following steps:

Create a new folder (if not already exists). For Firefox and Internet Explorer, the location is:

·         on 32-bit Windows operating system: \%WINDIR\%\System32\Macromed\Flash

·         on 64-bit Windows operating system: \%WINDIR\%\SysWow64\Macromed\Flash

For Chrome the location is:

·         %username%\AppData\Local\Google\Chrome\User Data\<profile>\Pepper Data\Shockwave Flash\system\

For Edge (recent chromium based versions), place the mms.cfg here:

·         C:\Users\\%USERNAME%\AppData\Local\Microsoft\Edge\User Data\Default\Pepper Data\Shockwave Flash\system\

In this folder, create (if not already exists) a file named mms.cfg and update it with the following content:



WhitelistUrlPattern=https://\<app URL\>/

AllowListUrlPattern=https://\<app URL\>/

You need to specify the top-level URL of the software you need to run.

You can specify multiple allowed entries by adding a separate WhitelistUrlPattern and AllowListUrlPattern pattern line for each of them, including port if required.


More details can be found in Adobe's Flash Player 32.0 Admin Guide in Chapter 5.

Option 3 – HARMAN browser

For businesses that need to continue running a supported version of the Flash player on older software products based on Flash, Adobe refers them to the HARMAN browser.
