Firefox not opening my QVC account.
I have been using Firefox as my browser for years to open my QVC account. Last night, while looking at my QVC account I tried backing out of the page I was on and I could no longer get back into my account. I tried using another computer and it worked fine. I also tried switching to Safari and again I could log into my account. I am using a MacBook Pro. I tried to refresh Firefox but that didn't work.
I can see the main QVC webpage but have no way to access my account or even open QVC. Firefox is working for everything else that I access.
Thanks for any help you can provide me.
