In the ongoing redesign project for Proton, developers from Mozilla plan to remove the compact mode for panel display from the interface settings (the "hamburger" menu in the panel -> Customize -> Density -> Compact), leaving only the normal mode and the mode for touch screens. The compact mode uses smaller buttons and removes unnecessary gaps around the panel elements and tab area to free up additional vertical space for content.
The reason mentioned is the desire to simplify the interface and offer a design that would suit most users. It is noted that the compact mode toggle is quite difficult to find in the settings and, according to the developers, few people use this mode (when analyzing telemetry, the developers overlook that people who change the default settings are more likely to disable telemetry transmission and thus drop out of statistics).
According to Mozilla, 93.3% of users use screens with a vertical resolution of 768 pixels or higher, so it was decided to use 768 pixels as the minimum height for optimization — 92 pixels will be allocated for the tab bar and address bar (in the new design, the bar will be thinner than it is now in normal mode). With the classic menu disabled, 88% of the vertical space will be allocated for content, not accounting for the operating system panels and not considering that some users do not maximize the window. Given the trend of modern websites to fix the header and provide a warning about cookie usage at the bottom of the dialog, which can only be agreed to but not declined, navigation on laptops with small widescreen displays resembles a view from a loophole.
