Getting Flash Player on Portable Firefox

Using only portable applications

>Direct to compressed version

As intro: Firefox 3 portable and Macromedia Flash don't play nice. In some chance that you have to use Firefox portable AND need Flash Player, you're out of luck. Well, not really, if you search around internet you'd find a way, just like I did. Now I'm going to increase information redundancy by posting the method to get Flash to be friendly to Firefox portable, in hope that it's going to be easier for lost souls to find the way -so to say.

What you need (with links):

Now that we have them ready, install your Firefox portable (if you haven't), and also 7-zip portable. The goal is this: we want to extract 2 files, flashplayer.xpt and NPSWF32.dll, from the Flash extension xpi file, and put them in Firefox' plugin folder.

Knowing the goal, the next step is pretty logical: open the xpi file with 7-zip archiver (right-click, open with (or open), browse, find your 7-zip install folder, choose 7-ZipPortable.exe), and extract flashplayer.xpt and NPSWF32.dll to Firefox plugin folder (...\FirefoxPortable\App\firefox\plugins\, with ... being where you installed your FirefoxPortable).

Exit Firefox if it's open, then open it again and navigate to a page with some Flash content for testing (and hopefully not procrastinating).

Compressed version:

Assuming Firefox 3 portable is installed

  • get 7-zip portable and Flash player extension (xpi file)
  • install 7-zip portable
  • extract flashplayer.xpt and NPSWF32.dll from Flash extension xpi file to ...\FirefoxPortable\App\firefox\plugins\, with ... being where FirefoxPortable is installed
  • restart Firefox

  14. Hi, I would just like to say that i have uploaded a portable ver­sion of fire­fox from to medi​afire​.com. I also have installed flash player with the method used above so all you have to do is down­load the zip and unzip it. there is no installer because it is com­pletely portable inside the folder extracted.

    the link is
