I have two other comcast email accounts that I can access normally but my home account after recognizing password will not progress beyond the "PREVIEW INBOX" page. Comcast has tried and all works fine on their end. I can access home account normally on Internet Explorer. Tech told me sounds as if Mozilla has become corrupted and I must completely uninstall and then re-install. Don't want to loose all my bookmarks/links/etc. Anything else I can do to fix this? Thank you.
