For non-Premium users, our payment page displays when we update the extension to keep you informed on changes we've made and as a reminder to consider upgrading to Premium. There is no obligation to upgrade, and you can dismiss the page by clicking the "x" on the browser tab. I appreciate your feedback about your experience with the update page and have made a note for our team. If you have additional feedback or questions, you can reach us at support@getadblock.com — Kat C., AdBlock Support
