Doesn't work at all for me, and it introduced me to a whole new failure mode for Flash: They load to the initial screen, which flickers like mad and would likely induce a seizure were I prone to them at all. My mouse cursor changes to a 'hand' when it's over the play button, but when I click it doesn't register at all. No sound, no change. (Firefox 4.0.1 from the repos on Natty x86_64 with flashplugin-installer 10.3.181.14ubuntu0.11.04.1 from the repos (latest; installed just this evening). I can do things like YouTube just fine; this is the only site I have Flash problems on. It is, in fact, the only site I've ever had Flash problems on in many years with Ubuntu.)
