1346350 - Firefox UI font has the wrong size in Fedora 24

Status: RESOLVED WORKSFORME

(Core :: Graphics: Text, defect, P3)

Description

[Carlos [nohamelin]]

The UI font used by Firefox for menus, tabs and others have a smaller size comparing with all of my other GTK applications. 

The attachment compares ESR 45.8.0 with current Nightly 55.0a1 20170310110248. Via mozregression, the issue go back to bug 1056479. Later, bug 1165179 fixes the font-type but not the size. Though why ESR 45 shows the font ok, I'm guessing the new rendering system is not enabled there.

It's a 32-bit Fedora 24 Xfce system.

Wrong UI font size in Nightly, vs ESR 45.8

The position of the dot above i in File suggests a different font still.

Running the browsers with FC_DEBUG=1 in the environment may provide some clues.

It seems? I forgot to mention that Droid Sans is my system font; adding the next to userChrome.css fixes it here:

> * {
>  font-family: "Droid-sans";
> }

Carlos, do you still see this when using a current version?

Comment 7

[Carlos [nohamelin]]

I'm not using anymore a Fedora system. Maybe someone can check it with a live USB.

Marco, are you able to confirm this exists or doesn't?

Not a problem anymore with Firefox 71 on Fedora 31.
