Sequoia update = font display unavailable
Hello, I have installed the Sequoia update on my iMac. Since the installation most of the font I use, especially if they are bold/italic... or using a font converter, appear in square shapped instead of text. This is only related to Firefox as it does no appear on any other browser I have opened the websites. I have cleared cookies and cache, but nothing works and weird fonts still appear (attached). Thank you for your help!
/edit: moved thread from Firefox for iOS (for iPhone/iPad) to desktop Firefox section as you have macOS
