Is there any way to locally include Adobe Flash with my Mozilla Firefox, Portable Edition? I'm using the one from

I need to do this so I can use my browser in another computer without installing flash. Or when I can't install Flash because I don't have administrator rights.

The guide in this page is outdated and no longer works with the latest version as of right now.

There are two ways to do this.

Method 1:

Following this guide: Flash player 11.9.900.117 for portable browsers (32 and 64 bits)

  1. Download the most recent Flash version as zip.
    The above blog author seems to update his post if new Flash versions appear
  2. Extract all files to ../FirefoxPortable/Data/plugins
  3. In Firefox, open about:config and set plugins.load_appdir_plugins to true (if not already is)

Test system was

  1. Windows 7 x64
  2. Firefox Portable (Aurora channel, 27.0a2, 2013-11-03)
  3. Flash Installed 11.9.900.117
  4. Flash Portable 11.8.800.168

Method 2:

  1. Download and install Adobe Flash for Firefox.
  2. Open Firefox and type in about:plugins
  3. Locate the directory of the Flash plugin and copy the ff. files: flashplayer.xpt, FlashPlayerPlugin_11_9_900_117.exe(or any equivalent for that version), NPSWF32_11_9_900_117.dll (or any equivalent for that version)
  4. Copy and paste those files to ../FirefoxPortable/Data/plugins

Be advised that LSOs (Local Shared Objects), commonly referred to as flash cookies, are still stored in a central location, depending on your OS, of course. That'd be %APPDATA%\Macromedia\Flash Player\#SharedObjects or %APPDATA%\Macromedia\Flash Player\\support\flashplayer\sys on Windows, for instance. – JC2k8 Nov 4 '13 at 11:43
Right after I last edited my question I went to my office's IT dept. to get some help about this and found another solution that does not rely on a repacked flash as a .zip. Instead of putting that answer here and selecting it as my preferred answer, I'm just going to edit your answer to include the stuff I found out and what @JC2k8 has just mentioned. Do you mind reviewing my edit afterwards? – Subaru Tashiro Nov 4 '13 at 12:46
@SubaruTashiro Go ahead, its fine. – nixda Nov 4 '13 at 13:00

I simply copied the NPSWF32_16_0_0_305.dll from C:\Windows\SysWOW64\Macromed\Flash and paste it to [YOUR_PORTABLE_APP_FOLDER]\Data\plugins.
