I used Bamboo Feed Reader Extension for some time. I can't think of anything I would have changed in it. While I was disappointed that Bamboo is not supported in recent relases of Firefox, I've found a satisfactory substitute in Feedbro. I hope that will become available in the Android version of Firefox as well. In any event, Feedbro will not function in Privacy Mode. Can this be overcome by future adaptations of Feedbro / other Feed Readers? Perhaps Privacy Mode and the underlying notions for creating Feed Readers violate an inherant conceptual premise in the Feed Reader schema - above my pay grade. Thanks.
