In this Ars article [arstechnica.com], Mozilla Corporation Chair Mitchell Baker discloses the desire to drop the Thunderbird email client altogether.
From the article: "Many inside of Mozilla, including an overwhelming majority of our leadership, feel the need to be laser-focused on activities [getpocket.com] like Firefox that can have an industry-wide impact [mozilla.org]."
Thunderbird has already been demoted to second-tier status, receiving only security updates since the summer of 2012 [mozilla.org]. Baker's plan would turn Thunderbird over to a community product, similar to what happened with the Mozilla Suite [seamonkey-project.org] a decade ago.
Is Mozilla's decision to laser-focus [venturebeat.com] on improving Firefox going to stop their dwindling market share? Who else, besides the submitter, is still using Thunderbird? And where will you go once Thunderbird is no longer supported?
