Wront font used for code display in Firefox #23421
-
Since yesterday my Firefox uses the wrong font (SF Mono Heavy) to render code on GitHub for example in the PR review. I have no idea why this is happening. I did not install a System or Firefox update nor can I remember making any other changes to the configuration. Also it works fine in Safari and Firefox displays all other websites correctly. I am on macOS 11.4 with Firefox 89. |

I could finally resolve this by removing (disabling) the font “SF Mono” in macOS’ FontBook app. |

Appreciate you tracking this down. I took the liberty of opening a Firefox bug report for this. |

And from that bug report: I had an old version of SF Mono (pre-Catalina, I think) on my computer. Downloading the latest version from Apple here and the problem has gone away. @greimers, can you check your font version/date in the inspector panel in Font Book? |
