flashplayer-plugin: added v10.09151 which is "Preview 1 of the new Flash Player 'Square'" and it comes in 32-bit as well as 64-bit. Essentially this is the folow-up to the withdrawn beta flasphplayer 10 for Linux.
xulrunner: added v1.9.2.9 - XULRunner is a Mozilla runtime package which you can install after removing seamonkey and seamonkey-solibs packages. It will provide support for compiling embedded browser components (and other stuff).
