When I'm clicking a link to a community on the instance I'm logged into (Lemmy.world), the community opens in my web browser rather than in jerboa. Given, this is annoying especially when I want to subscribe to that community.
I should note that I'm using a url checker app so this might be the reason for such behavior.
That's not how I interpreted it - I understood it as OP being logged in through Jerboa, and then clicking a community link, and subsequently having it open in the web browser, in place of opening in Jerboa.
