Perfect. Works in several places inserting my little descriptive screen. Today 07/20/2026 Amazon appears to have revamped payments completely, and it's not working anymore. No surprise! Hopefully the developer, Philippe Sabourin, hxxps://addons.mozilla.org/en-US/firefox/user/16640331/ will have time to fix.

Great extension to help keep track of multiple cards on Amazon! Thanks for bringing it over to Firefox
