I always use Firefox as my browser and I hardly ever have problems with it being incompatible with a website, including MC. It had worked with the new MC until last Wednesday or Thursday. Now when I try and get on using Firefox I always get an error. I thought the site was down until this morning when I tried to log on using Internet Explorer and it actually worked. Are you going to get the site to work with Firefox again? I prefer using that over IE. Thanks.
