Hey there.

I’ve been looking for a way to that would allow to easily switch between the original and the debug versions of flashplayer, without overwriting the original lib (as to not break the automatic updates), so here’s what I came up with.

First, make sure you have installed the general plugin. I have done this through Ubuntu Software Center (yes, I avoided terminal here, much more visual, i like that). Make sure to get the original thing by Adobe.
Make sure the original lib is there:
ivan@desk:~$ ls /usr/lib/adobe-flashplugin/ libflashplayer.so
For some reason, Flex4 OpenSource SDK does not include the debugging plugin (the thing provided in runtimes/10.1/lnx/ is a general version, not debugger), so get the “Flashplayer Plug-in content debugger” distro fromhttp://www.adobe.com/support/flashplayer/downloads.html
Untar the archive and move the plugin somewhere you will store it
ivan@desk:~/Downloads$ tar -xvzf flashplayer_10_plugin_debug.tar.gz ivan@desk:~/Downloads$ sudo mv libflashplayer.so /opt/flex4/runtimes/libflashplayer.debug.so
Now, install libflashplayer.debug.so as an alternative to libflashplayer.so
ivan@desk:~/Downloads$ sudo update-alternatives --install /usr/lib/adobe-flashplugin/libflashplayer.so firefox-flashplugin /opt/flex4/runtimes/libflashplayer.debug.so 60
Ensure that now the symlink points to the newly installed alternative
ivan@desk:~/Downloads$ update-alternatives --display firefox-flashplugin firefox-flashplugin - auto mode link currently points to /opt/flex4/runtimes/libflashplayer.debug.so /opt/flex4/runtimes/libflashplayer.debug.so - priority 60 /usr/lib/adobe-flashplugin/libflashplayer.so - priority 50 Current `best' version is /opt/flex4/runtimes/libflashplayer.debug.so.
Launch Firefox, type about:plugins into the addressbar and ensure that Firefox loaded the right flash plug-in.
