Will this work with 64bit systems? Or are we still stuck with the flash 10.0.32 alpha from adobe labs?
@no it doesn’t work on 64-bit systems
This is a somewhat more extensive way to install than when I tried the other day when it first appeared as available to try. That time I installed it following the given instructions but found that my browser (Shiretoko) was crashing whilst watching flash videos on BBC: Iplayer and CH4’s: 4OD. The controls in window were strangely distorted, button fonts too small to recognise except through instinct of previous builds, video was hard to start frequently with only audio playing.
@Aaron, you can get a 64bit Linux “pre-release” version of flash here:
http://labs.adobe.com/downloads/flashplayer10_64bit.html
Install is similar, it will contain a .so that you would put in ~/.mozilla/plugins after removing the Ubuntu installed version.
Note this is a 10.0 pre-release and NOT a 10.1 version.
It has worked well for me.
is it necessary to upgade the flash player plugin?
if your flash player is working fine theres no need to mess it up.
dont fix if its not broken…
It might actually be useful for ubuntu users IF it had video hardware acceleration for linux.
Screw flash. Come on HTML5.
