At a glance, this extension appears to also work with Waterfox Classic 2019.12. Maybe reduce the strict_min_version from 57.0, to 56.0? TIA

Is A11yFocus Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

A11yFocus requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
