Hi, try turning off 'Enhanced Tracking Protection' for that site by clicking the shield icon at the left-hand end of the address bar while the page is loaded - [[Enhanced Tracking Protection in Firefox for desktop]]. If that doesn't help, disable any ad blocker you may be using then reload the site. --------------------------------- Try deleting ALL references to Amazon. To do that, open the 3-bar menu > Library > History, then click the Show All History link at the bottom of the list to open the History-library window. Search for Amazon in the Search History field at the top-right corner. Now in the search results, right-click on Amazon, and select Forget About This Site. (Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed). Give it a few minutes to complete the deletion, then try the site (not from an old bookmark) again. More - [[Delete browsing, search and download history on Firefox]]. ----------------------------- Hold down the Shift key when you start Firefox to start in Safe Mode. More - [[Troubleshoot Firefox issues using Safe Mode]]. If it works in Safe Mode, disable any theme or extensions you have - 3-bar menu > Add-ons > Themes/Extensions, then restart Firefox; now if it's still OK, re-enable them one by one until you find the culprit. You may need to restart Firefox after enabling some extensions. ''If your question is resolved by this or another answer, please help other users by marking the best reply as Solved. Thank you!''

Thank you. The problem was that there was an extension enabled for "Amazon Smile". I removed it and it was fine. Thank you. https://chrome.google.com/webstore/detail/amazon-smile-redirect/ejglonclnjogoiegggjjcpapffbnangg?hl=en
