My website looks good on the mobile version, but the problem is that my desktop version looks like my mobile version. I’m not sure how this could happen. When I make changes on Shopify, the desktop version appears correctly. However, when I visit my website, it doesn’t display properly. Can someone help me with this?

it’s only on my laptop and if I use another browser it’s working correctly. It was a extension I needed to remove.
