As a new user, I’m disappointed with the Firefox interface.
The header or top bar is too wide, obscuring a bit more of the area that could otherwise be used to display web content.
Take a look at that screenshot;
Chromium-based browsers on Android have a slightly narrower top header, so more of the web content is visible.
My suggestion is that the standard Firefox should have a header or top bar style similar to Firefox Focus, which has a more compact design.
The second issue is that the browser menu (accessed by clicking the three dots in the top-right corner) appears from the bottom up.
I would prefer the menu interface to be positioned at the top edge, similar to most Chromium-based browsers.
This would make it more comfortable for users accustomed to the Chrome interface and others, and indeed such a design is more convenient than placing it at the bottom, as the hand does not have to move downwards after pressing the menu button at the top.
However, for me, the issue of the header or top bar being too wide and taking up too much space is extremely annoying.
I hope Mozilla fixes this soon.
I’m also reluctant to set Firefox as the default browser on mobile devices due to the interface design being less efficient and slightly less familiar, as the majority of people use Chromium-based browsers.
Otherwise, I really like Firefox, particularly because of its extensions, such as uBO.
