css3 - How to get user-modify:read-write-plaintext-only behaviour in Firefox and IE -

chrome/safari support css:

-webkit-user-modify:read-write-plaintext-only , can disable user paste rich text contenteditable div.

i not know how in firefox , ie.

i believe can use -moz prefix firefox

-moz-user-modify: read-write-plaintext-only; 

and ie (10+) can use -ms prefix

-ms-user-modify: read-write-plaintext-only; 

it proper add without prefix future proofing ;)

user-modify: read-write-plaintext-only;
