Handbook browser section.bigtoque said:I fixed the problem.
I assume the problem was that there was another flash plugin being loaded at the same time. Something called "flashplugin-mozilla 0.4.12"
There was a file called libflashplayer.so in /usr/local/lib/browser_plugins
There was a file called libnpflash.so in /usr/local/lib/browser_pluginsflashplugin-mozilla
There was a file called libnpflash.so in /home//.mozilla/plugins.
I just renamed all the files (just added a placeholder extension ".old"), restarted firefox and everything works great now.
% pkg_info -Ix flash
% pkg_info -Ix flash
