In my case where I have Bromite as a default browser it does not open links on it, rather on the say Android browser. This only happens in Lemmur. If I click link on another app, Bromite opens.

The open in links in posts works the same. I want to click the link and read them on Bromite.

Is it clearer now ?

Yes exactly that. I would like to open the link in my browser not lemmur’s internal one.
