Info about Plugins in Portable Browsers

I don't suppose we could have a stickied topic dedicated for those constantly asking about getting plugins to work in the various portable browsers. I've seen a number of posts regarding them, mostly about Flash and VLC.

Here is some information I can contribute in this regards:

• Google Chrome Portable comes with its own Flash plugin (PPAPI) and since version 45, has dropped support for NPAPI plugins altogether.
• Firefox 52 has dropped support for all plugins except Flash. This also means the 32-bit Java Plugin from JPortable as well as Java installed on OS is no longer supported, as it is a NPAPI plugin.
• Opera dropped support for NPAPI plugins with version 37, being based of Google Chrome/Chromium. To use Flash, reference https://portableapps.com/node/58446 for more details (Thank you, Coool for the info).
• SeaMonkey, despite being based on Firefox, as well as Quipzilla still supports all NPAPI plugins.
• Firefox Portable comes with both 32-bit and 64-bit Firefox. 32-bit Firefox can only use 32-bit plugins and 64-bit Firefox can only use 64-bit plugins. 64-bit Firefox prior to version 52 only supports Silverlight and Flash as plugins.
• Firefox Portable can have its 64-bit mode disabled in two different ways, with details found https://portableapps.com/support/firefox_portable#32and64 (Firefox Portable's Support page)
• Flash can be installed into Firefox Portable and SeaMonkey Portable as an addon called PlayFlash, which comes in 32-bit and 64-bit versions. This allows those who do not have install privileges to install Flash, but only for the browser. Its recommended to disable 64-bit mode unless user is sure Firefox will always run in either 32-bit mode or 64-bit modes. As of Firefox 57 (Quantum), the addon is no longer supported.
• Plugins is becoming a dying technology for the web, due to HTML5 and various APIs. For the stubborn, use a browser that still supports any NPAPI plugins, such as SeaMonkey, or an older version of browser that does. Keep in mind that using older versions of browsers is a security risk.
• In regards of VLC in Firefox and Seamonkey, Firefox must be a version prior to 52 and run in 32-bit mode. VLC's plugin files is not enough, where having almost the entire VLC progam in the [Appname]Portable/Data/plugins to work. This is due to the plugin not finding the required files for playback (codecs) and the graphics used for the player controls.
• Most browsers require to be restarted to detect plugins recently placed. So if you copied a plugin to the browser's plugin folder while browser is still opened, please restart.
• The location of the Flash plugin may vary by Windows version and whether its 32-bit or 64-bit. On windows 7 64-bit, the location of the 32-bit Flash plugin is located "X:\Windows\SysWOW64\Macromed\Flash\NPSWF32_25_0_0_127.dll" and the 64-bit is located at "X:\Windows\System32\Macromed\Flash\NPSWF64_25_0_0_127.dll" (path name seems misleading). The numbers in plugin name may vary by version of flash (example used is Flash 25.0.0.127). You can copy these files in [Appname]Portable/Data/plugins. If any one knows the locations on other versions of Windows, please share

Information in regards other browsers, as well as locations of the 32-bit and 64-bit Flash plugins on various versions of Windows would be quite helpful as well.
