I thought it was better than Dark Reader, but after the latest update it's giving errors on some pages like Facebook or Instagram when the page reloads after logging in.
Edit: I edited my review because the extension has good support and attention from the developer.
Thank you for bringing this to our attention. The issue affecting these sites was caused by an update aimed at enhancing the support for more websites. It was an unintended mistake, not a fundamental bug. We’re addressing it, and a fix has been released in version 1.6.6.
