My firefox version is 78.9-esr As attachment, Japanese and Chinese character will be messed up. I have tried to install different fonts like fonts-arphic-ukai and fonts-arphic-uming, but it still displays improperly. By the way, it can displays Japanese and Chinese in html correctly.

I think it is something wrong in profile, because I download the firefox from "https://www.mozilla.org/en-US/firefox/all/#product-desktop-release" and it work fine with default profile. But when it use old profile I assign to firefox, it will be wrong.

Thank you.
