Comment 0 for bug 1874842

Ubuntu Linux 20.04 LTS upgraded from 18.04 LTS, Firefox 75.0 (75.0+build3-0ubuntu1, amd64)
When viewing some sites such as facebook or github the fonts are not being displayed correctly. Other system fonts are used instead. The expected result would be to have fonts displayed correctly w/o unneded system file modification if possible.
