using latest 64-bit Flash player
The newest 64-bit build of Adobe Flash Player is the “Square” beta, downloadable here: http://labs.adobe.com/downloads/flashplayer10_square.html
After untarring and moving the libflashplayer.so into my /usr/lib64/chromium-browser/plugins the Adobe test page shows I’m running Flash version 10,3,162,29. I’m using the Chromium daily builds PPA for Ubuntu: https://launchpad.net/~chromium-daily/+archive/ppa so my current Chromium version is 10.0.607.0(68819)
This is on Ubuntu 10.10 64-bit desktop.
This version crashes less often than the built-in Chrome flashplayer. But sadly the “about:flags” click-to-play setting doesn’t seem to have any effect on the 10.3 flashplayer.
