After upgrade to 73.0 some fonts are not rendering or cascading to next font-family definition like other browsers.
On my cPanel login page, the body font-family definition is being overridden by an inline style
body { font-family: "Gotham SSm A", "Gotham SSm B", "Gotham", Arial; }.
"Gotham SSm A", "Gotham SSm B", and "Gotham" are not defined elsewhere inline or any linked style sheet. Every other browser on my Macbook (OSX Catalina) displays the page with the body font as Arial, skipping over the Gotham variants. Firefox seems to be trying to find them or is displaying boxed ? marks in place of missing glyphs. It is a nuisance really, I can just not use Firefox or defeat the inline override for login page because it does not occur on cPanel once logged in. But the glitch is there and I would like to know where it is coming from if possible. Gotham font is present and active on my Macbook as well, but not Gotham SSm A and B (ScreenSmart)...

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Is this with all websites/pages, some, a few?
Type about:preferences#content<enter> in the address bar. Across from fonts and colors, press the Advanced button. On the bottom, turn on Allow Web Sites To Choose Their Own.

So if I restart in safe mode and it fixes issue, does that mean one of the plugins is contributing or causing this issue?
Disabling Hardware Acceleration seems to have solved it. When restarted, the login now comes in clean and finds the fonts as it should from system library.
Thank you FredMcD!
Glad to help. Safe Surfing.

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.
