In some apps (Google News, Read - Simple RSS Reader) when I tap on a link, it won't directly open in Firefox but in a simplistic viewer, supposedly also by Firefox. From there I only have two choices, close the viewer (which brings me back into the app) or open the actual Firefox browser. The problem is that all plugins are disabled in this viewer, so I always need two taps to open a link from those apps. How can I disable this viewer?
The menu entry says 'Open with Firefox' and the small gray text says 'Provided by Firefox'.
I have Firefox 68.3.0 installed, but the problem has existed for a long time.
