Update 5/14/13. Firefox 21 is officially out today and has H.264 enabled by default, so you can skip the steps below.
----original post follows----
Fellow Firefox users, Firefox 20 is out and finally supports H.264 video (provided you're on Win 7 or above)! This means you can finally watch Giant Bomb's HTML5 videos. I tried it out and it works absolutely fine.
For those wondering why they should use the HTML5 video player, it's because it allows very high quality (unlike the streaming player) and yet also still allows skipping ahead without being fully downloaded (unlike the progressive player).
Note that H.264 is disabled by default in FF20 (technically, it's still in testing, but it works fine). To enable:
- First, make sure you're on Firefox 20. Click the Firefox button -> Help -> About. If you're not on 20 this should trigger an update.
- Type about:config into the address bar.
- Say you'll be careful (i.e. click past warning message).
- In the search box, type foundation, you should get back one result named: media.windows-media-foundation.enabled
- Double click the row to switch the setting to true.
- Close and reopen Firefox and you're good to go.
