This extensions is good but breaks Google Calendar causing Event/Task title not saving when creating new item. If somehow it can handle site exceptions it would be great.

Is Disable Page Visibility API 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.

Disable Page Visibility API requires a few sensitive permissions. Exercise caution before installing.
