Trying Brave at the moment and it's either confirmation bias or it's just really fast. Would you mind sharing how you changed the actions to use Brave? Cheers
Edit: I've just found Is It Possible for Keyboard Maestro to Support the Brave Browser? - #5 by peternlewis so I'm going to try Peter Lewis' suggestion from there now and see how it goes.
Edit2: No luck with changing applescript names in KM to either Brave Browser or Brave. I might be going about it the wrong way?
