I deal with www.vistaprint.co.uk The website opens, but I am unable to log in as the page freezes. I phoned Vistaprint and they told me never to use Firefox as it has problems, but to use Chrome. www.vistaprint.co.uk works normally with both Chrome and Windows Edge, but I prefer Firefox. Why do sites not work properly with my preferred browser - Firefox?

I have several versions of Firefox and had no problem.

When exactly does it freeze?

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
