Text does not display correctly after updating to Ventura
Yesterday, I updated to macOS Ventura and since then quite a few websites do not display text correctly in my Firefox desktop browser, including Mozilla interfaces (screenshots attached). I can copy these texts and paste them to some text editor file and I'll get a correct text. So it looks like only the graphical representation is affected. Also, bold and italic texts are always displayed correctly, h1 headings are not, h2 headings are... I browse on a MacBook Pro 16-inch 2021, Apple M1 Max, and I have the latest Firefox version installed.

sorry, the second image did not upload correctly previously.
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.
Thank you for the tip with the Inspector. I realized that when I change the font size from 14 px to 15 px, the text displays correctly. Since I did this, the websites that previously showed a mangled paragraph font now display correctly.
