Hi, I just switched from Chrome to Firefox. Everything is fine except this feature. On Mac, you can set a text replacement in System Preferences > Keyboard > Text and use it in any input in any programs. It works with Chrome and other programs that have an input field. Unfortunately, it doesn't work in Firefox :/ Is it possible to implement this? I would love to see this feature in Firefox. I saw there are some Add-on for this, but I don't want to use them as there is already a feature in Mac. I added an example screenshot. When I type "mymail", it automatically suggest what I set up before. Thanks, best wishes.
