I have a new Macbook Pro with the latest OS. It doesn't matter if I use Safari or Firefox, some items on QVC will not load for me. It seems to be mainly electronic items. If I do a search, the search page comes up, but if I click on an item, it will go to it but will stop loading. To order the latest Shark vacuum TSV, I had to use my tablet to watch the video and order. Same for the last LePan TSV. I can load, watch, and buy most other items but can't most electronics. I have cleared history, caches, etc., shut down the laptop and so forth, but electronic items will not load. ETA...QVC is the only website on which this occurs.
