Hi, In Ubuntu 11.04 AMD64 installation, I had to manually install Mozilla Seamonkey 2.1. The Mozilla Seamonkey 2.0.14 available in Ubuntu update repository did not work properly. The plugins directory which used to be there in the application directory structure is missing. I can not install adobe flash 64 bit version manually in this version. In earlier version I used to copy the libflashplayer.so in the plugins directory (/usr/lib/seamonkey-2.0.13/plugins/) I installed the Adobe Acrobat Reader plugin, and it installed the plugin nppdf.so in .mozilla/plugins folder of my home folder. I copied the libflashplayer.so in the same directory, but it does not show up in the about:plugins display nor does flash work. A web search in Google did not give any indication. Can any one point me to the correct directory to install plugins in Mozilla seamonket 2.1 Thanks and regards. sadhu
