When the browsers update and add support and there is no need for my older vender profixes, I can remove prefixes or I must do so?

Question

Vender prefixes

Answer 1

No. you must update your code.

Answer 2

ok

Answer 3

You shouldn't have to because the correct code is what the prefix represents. The prefixed code will be ignored and the updated code will perform without any adjustments needed (except if the browsers change dramatically, though not likely)

Answer 4

update
