HTML5toggle is a Firefox extension that provides a button which makes it easy to turn on or off the HTMl5 support in Firefox 4. Given that HTML5 support is still evolving, some websites do not work as expected when HTML5 support in Firefox 4 is enabled.
For example many early adopters of Firefox 4 have problems with Hotmail. Turning off HTML5 support enables such users to use their Hotmail accounts.
