Some time ago I removed a website form the New Tab Top Sites list. I'm pretty sure I did it via the '. . . > Delete from history' option. At the time I got a warning message similar to 'This action cannot be undone'. That was fine, but since then I cannot visit the website directly via the address bar or via the link that tends to appear in New Tab > Top Sites. What I've been doing is searching on DuckDuckGo then clicking that link, which works fine. That search is conveniently on my Top Sites list. I can access the site direct in another browser. I recently had to reset my password for the site and now the reset link doesn't work. All the help I've found doesn't mention any problem like this. How do I unforget/undelete/unblock this site? Help!
