So I got sick of how bad DDG browser is, so I finally switched back to FF and kept DDG just for app tracking blocking. I have uBO added and all set up. The pages are now beautiful. It's like a whole new internet! However, when I click on links in apps, it doesn't open directly in FF, some sort of Intermediary browser (run by FF) opens the page with a menu that has the option to "Open in Firefox". FF is my default browser. Everything is set to not open links in-app. How can I make this stop and the links open directly in FF?
