OK, that mental overhead of "last used browser" would drive me nuts.
My solution is: The system has a default browser that opens default links. On my work machine I have a different browser where I am for example logged in to my private github account I just never want to open a clicked link there anyway. Copy/pasting 2 times per day is fine.
so youre just manually doing what i automated but that 1% of the time when it opens in the wrong browser is too much mental overhead? if youre at work and you tap a link you were almost certainly last using your work profile so its nearly always right and its not something i ever have to think about
