How can I be assured that the Extension Dark Reader for Safari 1.4.3 that can be downloaded from Apple App Store will not read sensitive information from webpages, including passwords, phone numbers, and credit cards? I downloaded it for $4.99+tax but have not opened it yet since I understand Extensions can be dangerous. Thank you for any assistance.
I need a reasonable reason of why this Extension is safe to use because my eyes need it to view webpages in dark mode. The brightness on my MacBook Air M1 is killing my eyes. Please help.
