Renumber figures as they appear in text

Renumber figures as they appear in text

I have two questions:
When I use figure*, latex sometimes places the figure before its
predecessor. Is there a way to automatically number the figures as they
appear in the text?
On the other hand, is there a way to enforce the figures order? I tried to
put \FloatBarrier before each figure, but it messed up the document. I
don't mind it to float past a specific point, but I do want it to keep
them in order.
