Clearing cookies and cache, as you mentioned, is a good step. I’ve found that sometimes browser extensions (like ad blockers) can also interfere with the site’s loading times. You might want to try using a different browser or disabling extensions temporarily. As for the "unsecure" issue, it's probably related to certificate updates on their end. Clearing data helps because it forces your browser to refresh everything, but hopefully, that’s something LEGO can improve on. I've noticed the LEGO website can get really slow, especially on Firefox. Sometimes, clearing the browser cache or disabling add-ons helps, but if it’s still crawling, consider a fresh start with the browser. Uninstalling Firefox and reinstalling it often resolves lingering issues. If you’re unsure how to completely uninstall, this guide is about how to uninstall Firefox https://setapp.com/how-to/uninstall-firefox can help. Once it’s reinstalled, the LEGO site tends to work much smoother. Hope this helps!
