It’s not that you only play flash files using a flash player on your system, even while browsing internet and surfing web pages, you load up flash items on your browser, or even while paying videos on sites like Youtube, you need to have Flash support. But if you don’t have any flash player installed on your system or even don’t want to try one, then you can simply install a Firefox add-on to play flash files o your system.

You need to have a different version of Firefox for this purpose and it’s called portable Firefox. You can download Portable Firefox here.

Playing Flash files without Flash Player

1. Install Portable Firefox on your system
2. Download FlashPlayer .xpi from MacroMedia
3. Rename the downloaded file name to flashplayer-win.zip
4. Extract the archive now and copy flashplayer.xpt and NPSWF32.dll files
5. Paste the above copied files in C:\Program Files\FirefoxPortable\App\Firefox\plugins folder (I assume that C:\ is your installation folder)
6. you are done.

Now you can easily play flash files without installing a flash player. This trick supports flash videos, flash games, flash advertisements etc.
