exactly wtf is up with this website, firefox doesn't show t's, random f's, d's - it's a complete mess.
firefox doesn't show
I'm using the Firefox Developer version on Windows and everything renders correctly for me. I tested Firefox on Android and everything is present there as well.
No issues here on Firefox 146 Fedora/GNOME. Also imagine it's not uncommon for a personal site to not test for Safari if they're not in the Apple ecosystem.
As a fellow Fedora/GNOME user, fun fact: GNOME Web uses the same web engine as Safari! They both use Webkit, so it's not out of reach.
FF working as expected for me on Ubuntu
My best guess is that the font I am using (WOFF2 variable font) might be tripping up the browser.
That's probably it. I am getting these problems with Safari 17.6, with a newer one, Safari 26.0.1, there is no problem.
