I noticed that the same plugin behaves differently in mozilla and firefox:
File name: libflashplayer.so
Shockwave Flash 6.0 r79
It is slow in mozilla, but fast in firefox! However, another machine has firefox built by linux packager (http://altlinux.com/
), and a newer plugin version (r81), but it is slow. "Fast" firefox was downloaded from mozilla website. Both are versions 0.8.
