FlashToHTML5 is an extension for the Safari 5 browser.
We all know: the standard YouTube Flash Player eats up a lot of CPU and internal memory. That's why the FlashToHTML5 extension was released.
If possible, FlashToHTML5 will replace YouTube Flash Player with an HTML5 reader. Not only does this utility have a nice looking interface, you can also see your computer running faster and more stable. If you use a laptop, you'll notice that the battery capacity will increase when fully charged.
In addition, FlashToHTML5 can automatically play videos at the highest quality possible. The only bad point of this application is that it does not display user subtitles and captions (to be improved soon).
Some videos on YouTube will not be viewable due to a format not supported by this gadget. However, FlashToHTML5 will automatically revert to the standard YouTube Flash Player.
