@[user name] only works in Chrome?

Question

Hi,

if we use the @[user name] in Chrome Browser it works. After typing the @ a list pops up. In Edge, Internet Explorer, Firefox and Safari the list doesn't pop up.

Is this a setting in the browser? How to enable this feature, so it works same as in Chrome?

Regards
Stefan

Update: I logged in with the other user name on my PC in Chrome Browser. And there also was no po up list after typing the @ symbol. So it seems to be a user setting, or user right!?
