Getting Flash to work under Chromium on Fedora
I had already downloaded and installed Flash for Firefox, following these instructions but could not get it to work as a plugin on Chromium.
Success is yours when you type "about:plugins" into the location bar of Chromium and the Flash player appears.
Fortunately, it turned out to be pretty simple to just link Firefox's plugin into Chromium: As root, do this:
cd /usr/lib64/chromium-browser/plugins/ ln -s /usr/lib64/mozilla/plugins-wrapped/nswrapper_32_64.libflashplayer.so .
