I tried and keep trying Photon Browser for NSN only and work okay, but the program seems to crash a lot, is free with ads frequently and there's a free ads version for $6.99 a year. Is the only one can can run flash for NSN so I think worth the try.
Are we talking about viewing the podcasts and videos from the NASA site? I'm not having any problems viewing either with Paranoid Android 3.10 (Android 4.2.2) and Firefox. Have they switched from Flash to HTML5?
