I know this has been all said on the last few pages but I just though I'll pull it all together in single noob (hopefully!) friendly post... So, in order to have flash player v10.1 working with youtube and embeded facebook videos here's what I did: 1. Remove old flash player, type in terminal as root (OPTIONAL): Code: apt-get remove --purge adobe-flashplayer 2. Download new version from (link provided by pinochio): Flash Player v10.1.98.88 3. Install Flash using: Code: dpkg -i /path/to/adobe-flashplayer-10.deb 4. Bump the version up by faking it through hexediting: I've used hexedit available for n900 which you can get with this command: Code: apt-get install hexedit type this to hexedit libflashplayer.so: Code: hexedit /usr/lib/browser/plugins/libflashplayer.so 5. Once in Hexedit, press CTRL+S and type in 31302e31 and press enter, the string you've just found need to be changed to 31322e31 6. Now, press CTRL+S, type "y" and search for 31302c31 and change it to 31322c31 7.Press CTRL+S then "y" again. Close terminal and enjoy new faked v12.1.98.88 flash player
apt-get remove --purge adobe-flashplayer
