Doesn't work with Firefox 116.0.3 with the latest extension update available installed. It just gives the following error message "Error: Refresh or try again later" every time, on every article tried.

Extension safety

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.

Who Wrote That? requires a few sensitive permissions. Exercise caution before installing.
