How to get custom change: read-write-plaintext-only behavior in Firefox and IE

Question

Chrome / Safari css support:

-webkit-user-modify: read-write-plaintext-only, which can disable the insertion of rich user text into the content div.

I do not know how to get it in firefox and IE.

Answer 1

I believe you can use the -moz prefix for firefox

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

And for IE (10+) you can use the -ms prefix

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

It would also be advisable to add it without a prefix for future verification;)

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