After re-starting my iMac the wrong characters appear for non-letter characters such as punctuation, which you can see in the screenshot from the pocket recommendations on the home page, where the issue doesn't appear too bad, but in practice trying to use any site with form inputs asking for email addresses etc. is impossible.
This has happened in the past and I have somehow been able to fix it, but this time nothing I've done helps. (It's only ever Firefox that is affected.)
I have deleted the app and re-installed it. I have cleared cache and cookies. I have cleared all browser history etc. I have tried changing fonts from the defaults. I'm not sure there are any other troubleshooting steps I can take.
I'm using FF developer edition, current version (just re-installed it, but it is always up-to-date, and this has been happening for a year or two). MacOS 12.6.3.
I'm a long-time FF user and until now I've lived with this inconvenience as I've somehow fixed it after troubleshooting steps, but this time I can't stumble upon the solution.
