Comment (by heyjoe):

 I know about `layout.css.devPixelsPerPx` and I have tried it before using
 `zoom.minPercent`. Although it works the result is weird. For example
 setting it to `1.5` zooms all interface elements but the font of the text
 in the address bar, search field and bookmarks bar stays the same and as a
 whole the font in these fields is way too small. (Is that probably another
 bug which should be reported separately?) So basically it creates big
 elements with tiny text which is practically a waste of space for gaps.
 That's why, considering that UI fonts can't be scaled, I decided to use
 `layout.css.devPixelsPerPx` and at least not waste space for increasing
 gaps. One is basically forced to choose between two options neither of
 which works as expected.

 Just for comparison: Testing in Chromium browser with `--force-device-
 scale-factor` works fine - everything is zoomed properly (fonts of UI
 included).
