Arial Font disappeared from Google Docs/Spreadsheets on Firefox
Since the latest Firefox Update (Version 86.0), the Standard "Arial" Font has been missing from Google Spreadsheets (and Docs) and has been replaced with the inferior "Sans Serif". IIRC, this has happened once in the past (after a Firefox update), but was corrected after a few days. Is there any way to add Arial again or does one simply have to hope this issue will somehow be fixed in a future update?
I should add that this only does occur when using Firefox + Windows, any other combination (like with Chrome on Windows or Firefox on Mac) does still display the original font.
