This article has been updated in 2014 to give a testing link for the khronos project. The original article continues below.
Today has been a little bit of an experiment.
My regular browser is Iceweasel 4 (Firefox 4), and I am bending the rules of the angry birds beta, by using my browser to beta test.
Use the 'SD version' and get playable results:
I don't know precisely which features of Firefox 4 are utilised, but for now I am just having fun completing as many levels as I can.
But there is no sound in the 'sd version':
Remember that you are using a non supported browser against a 'beta' setup.
( If you are desperate for sound and / or the 'hd version' then chromium from the 'sid' unstable repository is a non-recommended option )
Hey if you've heard the background music once, you've heard it a thousand times, why not have libre.fm play you some background music instead :)
But I use Nvidia / Intel graphic card and cannot even play 'sd version':
I have only tested 'sd version' on two ATI equipped desktops, but I ask a question here to check that there are no issues for other graphics cards.
Iceweasel 4 freezes on loading on my machine:
Go directly to the 'sd version' url
( Note: I tested that 'sd version' url today, however being a 'beta' it is very subject to change )
If you still have no joy, then you are free to install firefox nightly and try that.
If you are able to participate in the 'beta' using either an official browser ( Chromium 9 / Chrome 9 ) or an unofficial mozilla browser, then have fun and enjoy this free game :)
