Vlad other than what optuma said, profiles also has another useful usecase. When you're using more than one browser, you'll be using a tool like OpenIn or Browserosaurus. When you click a link in Apple mail and then choose your preferred browser for that link from OpenIn or Browserosaurus or similar, it'll open the default container in firefox. No matter if you have a work / shopping container opened. It'll still open default container. So you're always exposed with this. But with profiles, if you have opened the profile in which you want the link to open, then it opens in that profile. I just tested this by having two profiles opened in Brave. The result was that the link is opened in whatever profile was last opened. Atleast it doesn't open in the default profile always, unlike in containers.
But containers has their usecases as well. It's very easy to right click a link within firefox and press "open link in new tab container" and then select which container you want that link to open.
So both profiles and containers have their use cases. And that's my point. Firefox has both profiles and containers. YES, firefox has profiles as well. Not many people know about this. But the profiles in firefox doesn't have the prompt that brave has, that prompt is absolutely amazing. Deleting a profile in firefox somehow doesn't delete the actual folders of that profile if you reveal it in finder. So the profiles in firefox isn't perfect.
How about we do things perfectly that other browsers don't? Orion can be the second browser to implement both profiles and containers, after firefox, but unlike firefox we can improve the profiles and make it work like brave. Then Orion will be the only browser that does it best for both the worlds.
Apple always waits for the competition to experiment with new technology then they are the last to implement that technology because they don't just want to release it hastily, they want to do it the best way possible. It's Steve Jobs legacy. So I think Orion should also follow this path and implement both but by understanding where both brave and firefox lacks and then we can do it better.
Hope this helps in decision!
