Why don't browsers autocorrect CSS3 transitions? The only difference between the Safari/Chrome and Firefox CSS transition is "moz" and "webkit". Surely firefox could just add an autocorrect feature to change every instance of "webkit" in the css to "moz" and the problem would be solved. Or is there something more?
Normally the -moz and -webkit are for CSS selctors are properties that are are specific to the the browser engine. The selector could be unstable, or act differently in each browser as they refine the behavior.
They don't want to "autocorrect" to the other implementation because the other browsers interpretation of the CSS property could be different. It could cause problems about what CSS property should "win" in the event of a conflict. Lastly, it could increase development time for each browser since they would need to figure out what the other browser engine is doing.
