Mozilla is working on a modernization of the Firefox interface as part of its Nova project. Several mockups of the new design are available, allowing you to evaluate the main trends.
The most noticeable change is the increased rounding of the tab buttons and address bar, as well as the consolidation of the top area with the tab bar and navigation bar, the sidebar, the web page content area, and the page elements shown when opening a new tab into separate, rounded blocks. The different blocks are highlighted with their own gradient colors.
