Browser rivals mock Microsoft's 'native HTML5' claims

"Mozilla should consider adding support for native HTML5 as well," said Mike Beltzner , a former director of Firefox who recently left Mozilla. "I'm sure that a specification will be produced."

Others quickly chimed in with more satire.

"I'm pretty sure Firefox 5 has 'complete native HTML5' support," said Asa Dotzler , Mozilla's director of community development. "We should resolve this as fixed and be sure to let the world know we beat MIcrosoft to shipping *complete* native HTML5."

When some participants in the Bugzilla thread seemed to take Beltzner's call for a Firefox bug fix seriously, Brendan Eich, Mozilla's CTO and the creator of JavaScript, reminded everyone of the joke. "The 'native HTML5' nonsense-phrase is a source of endless fun. Like this bug," said Eich.

Opera was mystified by the phrase, too.
