Dear Community, I love Firefox but here is how fonts now look like on my old MacBook Pro (v10.13.6). Why is this? How can I fix this? My Firefox version is up-to-date. As shown on the screenshots below, on Chrome fonts appear to be normal. Thanks so much for your guidance!

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 Font 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.

[v56+] Type about:preferences#general<enter> in the address box. Under fonts and colors, press the Advanced button. Scroll to the bottom, turn on Allow Web Sites To Choose Their Own.

Make sure you haven't enabled a High Contrast theme in the OS settings.

  • We have seen reports that this can be caused by a problem with fonts like Roboto or Helvetica that

you have installed locally and that might be corrupted or are missing some variants. Also, make sure you allow pages to choose their own fonts and that you do not block remote (downloadable) fonts.

  • If you use uBlock Origin make sure not to "block remote fonts".
