I'd like to share some feedback as a long-time admirer of Firefox. While I consider it the best browser available, the primary reason I recently switched to Edge is the lack of a critical extension that is exclusively available on the Chromium platform. I am confident that if Firefox implemented compatibility with Chromium extensions, it would be poised to become the world's leading browser. Additionally, the vertical tabs feature is exceptionally well-designed. I would strongly encourage the team to consider setting it as the default layout.
