This is a feature that Safari 18 has, and Arc Browser has (called Air Traffic Control). It allows me to control which profile opens a link (no matter what application it is opened from), based on the domain name.
EXAMPLE:
I have two profiles, Work & Personal. I am logged in to websites like X.com, YouTube, Amazon etc. in my Personal profile. When I click on an X.com link or a YouTube link, it will only open them in my personal profile, even if I last used the Work profile. My employer uses Microsoft services, so I use this feature to direct any work links to my Work profile like what happens with non-work links in my Personal profile
This is an incredible feature that I miss when using Brave.
See attached screenshots from Safari 18 & Arc. I would recommend an implementation similar to Safari’s. Bringing a feature like this to Brave now, would be a good way to take market share from Arc, since Arc is now in maintenance mode only.
