Is it a blank new tab, or link to a new tab? If a link, what is it?

it is a link to new tabs. I have opened them before and know it to be a secure site but now it always comes up with the message the "firefox has blocked the site. " If I click on the allow, it will then open.

Can you attach a screenshot? *http://en.wikipedia.org/wiki/Screenshot *https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem Use a compressed image type like PNG or JPG to save the screenshot. ----- Do you mean this: *Firefox > Options/Preferences > Advanced > General : Accessibility : [ ] "Warn me when web sites try to redirect or reload the page" The setting in "Options > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.
