This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Both are correct in their own context, but the first implies emphasis: "Well, which browsers do support this, then?!" Context is important: what triggers this question? – Andrew Leach Feb 6 '13 at 11:10
Ok. There's not much context. I was just wondering if one of those was incorrect. I have the answer then. Thank you :) – fiddler Feb 6 '13 at 11:17
@RegDwighт Sorry, I did not know – fiddler Feb 6 '13 at 12:19

The do form contrasts with a previous statement:

"You could use canvas, but not all browsers support it".

"Which browsers do support it?"

It's not restricted to the interrogative. It's one case of do-support.
