That doesn't really have anything to do with how it works though. I was looking more into its actual operation as a browser.

I use FF as well. I think the problem is lack of focus on core workflows. This is a problem with all major browsers.

For example, why is the address bar so tiny on high resolution screens? One would think this is an easy fix that would improve the UX for many people. Yet years go by with unresolved issues in the trackers.

Because in the year of our lord 2024, we for some reason still don't know how big a pixel is. Making a textbox 1cm tall should be trivial, but is for some reason either impossible or never done.

I would be happy to be able to adjust the font size. It's almost as if these orgs don't use their product...or the effort to make this small change would require a major re-architecture.

For a browser UI 1cm is NEVER a useful measurement. 1cm is useful if you are writing CAD software (which you could write as a web app so firefox should know what 1cm is only for purposes of supporting such web apps), so you can touch a physical part to your monitor and visually verify it fits before having a one off part made to do further verification of your design. For everything else what matters isn't the physical size, but if it is visible, which in turn is a function of how far away the monitor is from your eyeballs and your glasses. My phone, laptop, desktop, and movie room (I don't have all of the above, but someone does) all need different sizes of address bar to be useful.

What's high resolution for you? I'm using Firefox on a 32 inch 4k display and would not want the address bar to be bigger. Of course I could make it smaller / bigger thanks to Firefox supporting custom CSS

If management cared about the browser they would have never had this staff in the first place, a similar amount of staff for programming, testing, and marketing their browser would have been effective at making a better browser and getting more market share.
