I am a big fan of Firefox+Thunderbird and subscribe to Pocket, Mozilla VPN and Firefox Relay. I don't think she was the right CEO for the job, coming into the job because she was needed after the Eich debacle, not because she was the best choice. When I listened or read interviews with her I sensed a lack of focus, which I think came through with the lack of focus and commitment I sense in Firefox's products. She seems like a better fit for chair of the foundation, pursuing pie in the sky ideas rather than in the trenches trying to rebuild Mozilla's presence and diversify their revenues. Pocket has stagnated under their care, and actually grown less useful to the point I am considering switching. The Android browser is stuck in time. I don't think it's a coincidence that Thunderbird has flourished after pursuing a semi-independent structure: they finally had people who actually cared about the product calling the shots.
