You know, I really like the idea of upgrading tumblr’s built-in video player. I like seeing how long the video is before I watch it. I like that you can rewind a little better than before.
But I DON’T like it putting itself in full-screen when I press play, or crashing Firefox over and over again (I mostly use Chrome, but sometimes I’ll use Firefox for a change of pace). And it still loads videos just as slowly as before.
