I don’t think so I use Firefox (am now) and don’t have any issues. We did a have a certificate error a couple of weeks back as there was an error with my credit card, but that’s all sorted now. If you still have issues if your able to take a screenshot and post it using explorer Georgie can take a look at it for you.
It was more than likely a cache issue with the bookmark. If you have any troubles with this sort of thing in the future a simple cache refresh will fix it most of the time. For most browsers the shortcut is ‘CTRL’ + ‘R’ (Windows) & ‘COMMAND’ + ‘R’ (MAC). This will reload the page with the most up-to-date assets & fixes.
