Issues Accessing Custom Box Configurator on Packing Website Using Safari

Hello Apple Community,

I've recently been exploring a packing website that offers a custom box configurator tool. Unfortunately, I've been experiencing issues when trying to access this feature using Safari on both my MacBook and iPhone. The website loads fine initially, but when I try to customize the box dimensions or select design options, the page becomes unresponsive, and sometimes Safari even crashes.

I've cleared my cache and updated to the latest version of Safari, but the problem persists. Has anyone else experienced similar issues with Safari? Are there any settings or tweaks that might improve compatibility with websites like this one?

Thanks in advance for any insights!
