The Nokia N9 gets another treat from Nokia. Adobe FlashPlayer is now available for download at the Nokia Store or you can download it directly from this link (Note: Your Nokia credentials are needed to download). The plug-in currently works only with FireFox web browser for the N9.
Is the Nokia N9 keeps getting better, or what?!? 😀

is it just me but i have firefox and flashplayer downloaded but dont seek to be able to play flash. is there something i have to activate or do?
I did not do anything special. It works in my Nokia N9’s. There is a firefox mobile extension called Phony with selectable user agents. Just go to the extension screen of firefox mobile and search for it and install it.
