Improve YouTube video quality in FireFox

While watching movies on the iPhone version of YouTube I always noticed videos looked better. I just thought it might be the smaller screen. With this new Add-on for FireFox, I think it confirms that there are different quality versions of videos at YouTube. In fact, according to Josh, this Add-on streams from instead of This makes sense to me because Google videos always supported much better video quality. Perhaps the YouTube player on the iPhone does the same thing?

The Add-on for FireFox is called “Better YouTube Firefox extension” that really does improve the video quality of YouTube, depending on the video that was originally uploaded. I always upload videos in a better quality than is shown at YouTube, and I can confirm that it does work with a side-by-side comparison of two of my videos using Safari (left) Vs. FireFox (right) with the Add-on:

Here’s another that really shows off the difference. It’s a video I created last December, editing and uploading directly to YouTube using Apple’s latest version of iMovie, and you can really tell the difference in the titling at the bottom of the page.

The Add-on gives you some other cool features such as the ability to hide comments, show the full video description, and there’s even a “Theater View” mode which allows you to view videos at 750×580 resolution. The downside to theater view is that you have no other information on the page (description, comments, links, etc.)

This Add-on actually does nothing to improve the ‘stream’ of video. It can’t take a bad video and make it better. All it does is add or change elements of the existing YouTube page, such as where the video is downloaded from (Google Videos, not YouTube), and automatically does things that you can normally do yourself, such as click the More link to view the full description. A very worthy Add-on for FireFox!

    huh.. interesting note: our internal corporate internet filter is blocking the “HD” feed, seems to come from a different server, one attached to instead of

    That makes sense… Google videos always played at a higher quality. I’ll update my post with your info!

    I’m starting to notice that some videos don’t display at all. For example this video:

    It shows fine if I turn the add-on off, but if it’s on it won’t display. Perhaps it hasn’t made it to Google Videos yet?
