My page loads very slowly and awkwardly with the wrong fonts. Only several seconds later it manage to change to the correct fonts. This creates a really bad user experience. How can I fix this? I have already cleared cache, but the issue seems to be present still. When I tried to make the page builder company test it on their end, they also see the issue still, and they told me to reach out here to Mozilla for a solution, as it loads properly on other browers like Chrome, Safari, Edge and Opera. Thank you.
