When it comes to using icons on different browsers, I've noticed an issue. Icons appear sharp on Google Chrome and Opera, but when viewed on Firefox they tend to look blurry if the font-size is less than 20px. Strangely enough, once the font size reaches 30px or more, the icons appear smooth on Firefox. Is there a way to resolve this? For instance, similar to fixing the problem of blurry images resizing in Firefox by rotating them slightly, can a similar solution be applied to font icons?
To witness this issue firsthand, simply visit any website with icons (like Font Awesome) on Firefox, resize the icons to 20px, and observe how they become blurry.
