having unnecessary copies of files when links work properly in linux, plus I
suspect if I did do that I would still have had the problem anyway.
As described previously, you can avoid all the confusion by removing the flash
plugin entirely and re-installing it via the Adobe-provided .tar.gz into
~/.mozilla/plugins. You only need the libflashplayer.so. One file, one copy,
that's all. It won't get any easier.
