Ever since the "new" profiles were introduced (not to be confused with those you can access and edit via about:profiles - naming both profiles is immensely confusing tbh), the name of the profile you are currently using is added to the taskbar element. For example, if the support main page os your current open tab, the taskbar element will say: Mozilla Support- Profile name- Mozilla Firefox. I see no need for this, so I would appreciate an option to remove the profile name
