Mozilla did change several interface elements after the release of Firefox 57, recently the controversial address bar overhaul that it launched in Firefox 75 Stable.
He notes that Firefox will look more modern when the designs land and that Mozilla plans to introduce useful improvements, especially in regards to the user experience.
Be afraid. Mozilla has a history of turning attempts at being "more modern" into horrible UI solutions.
