I hope this is a step forward for Firefox and I expect that there will be some genuine wins in here, but I really hope this is not yet another redesign for a desktop app that tries to make it look like a mobile app by removing features and adding gratuitous amounts of whitespace. The word "streamlined" is usually the harbinger of such regressions.

Desktop is not Mobile and their interfaces should not be the same. Windows 8 showed us what a disaster that was, but every company since seems to have to learn this lesson themselves. (Looking at you spotify)
