It looks like this error is related to lack of support for your browser version with the Google Maps Javascript APIs iNaturalist uses. You say you are using Firefox version 94.01, and it appears that versions up until 98 will have the same issue (not sure if versions after that might have other issues as well).
If the change is recent, it may be due to an update of the Google Maps Javascript API that has introduced changes not compatible with older browsers. If you are unable to update Firefox, all I can recommend for the time being is to try another web browser, like Opera which you say is loading fine.
