Comment 11 for bug 252640

By that logic Gnome terminal, Firefox and Evolution (core apps) shouldn't have customizable font sizes. Gwibber deals with content (and potentially lots of it). I *don't* want my whole desktop to change just because I want more content in Gwibber. I agree the default should match the global prefs, but one should be able to easily customize this bit, specially in content-intensive apps.
