Custom font-family not loaded in Firefox

Hello there,

I have 2 custom font-families I use on my website - MinionVariableConcept-Roman, MinionVariableConcept-Italic. As these are all working good in Chrome, in Firefox they are not displayed at all. When I inspect page CSS, font-family is loaded, but whereever custom fonts are used, no text is displayed at all. I do use Elementor, but since it doesn't support .otf fonts, I have declared it in each element's custom css (e.g. .some-class h2 {font-family: 'MinionVariableConcept-Roman', Sans-serif;} instead of using Elementor's Typography) and it works inside Chrome, since those fonts are added inside Generatepress following the steps you provided in some of the previous articles. I really can't say why is there issue in Firefox. When I inspect css of the page, it looks like font-family property is loaded, but something stops fonts from being executed. I have read a similar topic on this forum, tried everything that guy tried (including checking my own Firefox settings) but fonts are still not loaded at all.

Thank you!
