I am trying to add or remove websites to Top Sites but everything return old saved profile settings. I do not have same problem with bookmarks. I can delete or add pages there. But nothing works with top site. I have tried clean install, removed all add-ons, removed Advanced System Care nothing works. It's working if i use new installed version without add my old profile. But i need my bookmarks and i like topsites i added previously (i don't want add all manually again)
