how do I paste formatted text from microsoft word?

Whenever I paste text from an external source, such as Microsoft Word, into a text box, I am told my browser settings require me to paste it as plain text in a separate window. So I have to reformat my text all over again. How do I adjust my browser settings, or what else can I do, to avoid that? I use Chrome, but will use any browser if that is an issue. Thanks to any and all who answer.
