The only thing I did to get the beta flash 10 (built against an older glibc it seems) working, for minefield was to copy libflashplayer.so to /usr/local/firefox/plugins/ . Nothing else was required. Aside: a lot easier for me to do each boot (I'm booting off of a CD) than using appbrowser to load extensions (tce-load fails, silently, for me .. still using TC 1.2).
