- some sites enter fullscreen mode for slide shows and having slide shows in smaller browser windows is not really a good experience
- can't play html5 youtube videos in fullscreen
- on vimeo.com when I disable flash plugin the videos are played using html5. However, when fullscreen api is disabled I am greeted with a strange warning:
What’s going on here?
Some of your technology may be out of date, and this video may not play properly.
Try Anyway
Example: http://vimeo.com/45917260
When I press "Try Anyway" the video is played in a dumbed-down player in a very low quality.
Considering the above, why would anyone want to have fullscreen api turned off if it only results in problems (not counting a handful of power users having their own strange reasons to do so)? I know this api is not complete in SM and still there is the narrow navigation and location bar visible but at least it works and I think it's much better than to have it disabled.
I'm thinking about filing a bug to change the default to true - would this make sense? In my opinion SM is not user-friendly in this respect if people have to hunt for some hidden preference just to make some site work well.
