web development: using background video is blocking firefox

i'm developing a website which is using a background video for the home page. that video has pretty small filesize (about ~300 kb) and the problem is that it is kinda blocking firefox - which means when clicking a link to a different page, it takes about 10 seconds until firefox will start lo开发者_开发知识库ading it. i've checked the taskmanager, plugincontainer.exe is eating ~26% cpu on my machine. any ideas how to optimize this?

I googled optimising video backgrounds, and it gave me this page, it talks about streaming videos and how to optimise it, its essentially what will be causing the problem I would assume.
