Which browser (if any) will be able to play video and audio at VKontakte (vk.com) in Ubuntu without a flash plugin?

http://askubuntu.com – I'm primarily concerned about this question for Ubuntu on Toshiba AC100 (ARM), because a Flash plugin for browsers is not available as a working package for Ubuntu on AC100, but it is a general question which would apply to any Ubuntu system where one doesn't want to use the prorietary Flash plugin and the format. At http://vk.com , video and audio are usually played by means of Flash. What if one doesn't want to mess with the proprietary Adobe's flash plugin, is it possible to play video and audio at VKontakte? (As we know, in the case of YouTube, video playback can be done by means of HTML (HowTos)
