I'm on 64bit Linux here, and as long as I used the Adobe Flash plugin, it regularly crashed (in various ways, most of the time just the flash subsystem).<p>I know there is a 64bit version now, but I got genuinely fed up with them, so I deleted the plugin and use swfdec for youtube and just don't care about the rest. Can't say that I'm bugged much, my browsing experience actually improved.<p>The main reason I boycott flash is still, that it is by no means sustainable and it inhibits the progress of the web a lot (get the feeling of a hamster in a hamster wheel, solving the same damn problems over and over again). It must simply die.
