I have a very frustrating problem, trying to update the Firefox (3.0.13) flash plugin in Elyssa (KDE). Everything is fine with the original
installation. On the 'about:plugins' page, it shows as ver. 10.0.b218, but if I try to replace libflashplayer.so in /usr/lib/flashplugin-nonfree/
with any later version, it effectively "disappears". Firefox doesn't find it. Same with Opera. I restore the original libflashplayer.so and
everything works again.
Any help much appreciated - I'm new to Mint, still finding my way around.
