I've attached an image. Installed Mac OS 13.0.01 Ventura on my iMac and now Yahoo Mail displays as shown in the attachment. All symbols, no readable text. I've been using Firefox for many years but I'm so frustrated I launched Safari this PM and Yahoo Mail opened fine. Hate to make the switch, but...

Any thoughts?

Thanks, [removed email from public]

You can check in Font Book for font issues like corrupted and duplicate fonts.

You can right-click and select "Inspect" to open the built-in Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Fonts tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.
