Macs have the ability to set Text Replacement. Macs come with some default Text Replacement; for example, omw is automatically replaced with On my way!. You can edit and adjust these replacements. I have it setup so my full phone number, address, and email address etc are substituted when I type certain things. For example, I set a Text Replacement to replace the first few letters of email address with my entire email address, to replace the number portion of my address with the entire address, etc. This works in MS Word, Messenger, etc, but it does not work in Firefox. I understand this does not work in some Applications unless it is enabled. How do I enable it in Firefox?

Thanks
