When I try to open Options from the Keepa's Add-on page in Firefox, I get the following error:

Bei Amazon sehe ich sofort, ob ich besser mit dem Kauf warten soll. Dank der variablen Zeitachse kann ich den nächsten Tiefstpreis abschätzen oder den Preis-Alarm einstellen. Mir gefällts!

I love this add on alot! I used to stab myself in the eye but this addon made all that nonsense stop and IT also helped me considerably with my stuttering problem!
Thanks keepa amazon.com price checker!

I love it and I've been using the addon for years. Thank you, great work!
