Criticism is not disrespect. To want to end disharmony by calling it disrespect is neither right nor helpful.
I myself worked on the (now rightly scrapped) rendering engine back in 2001-2003, mainly constructing and providing test-cases, but also contributing a few lines of code here and there, so I am emotionally invested in Mozilla. Decisons made increasingly less by the community and more by “The Foundation” are threatening the future of an open internet. Assuming a position in which one can make decisons (project leaders, developers, etc.) also means having to assume responsibilitiy for those decisions and thus having to listen to the criticism that results and reply accordingly. This is what is happening here, nothing else.
I would welcome two responses by the foundation: 1. We are working to bring back support of any and all add-ons to the the Firefox releases, our goal is e.g. the Beginning of Q1/2021. 2. We messed up, we realised that now, please bear with us while we fix this.
I don’t need an apology for my ego, but it would underscore the pledge to bring back what made FF what it was, an integral piece of the open web.
