More details wouldn't hurt. See my profile. One site (name that site) or all sites.

Whenever I click on a link, I always get a message saying "Firefox prevented this page from redirecting to another page"

I then have to click on the 'Allow' button, and it goes to the page I wanted. This is extremely annoying. I can't find a setting in Firefox that will fix it. I never had this problem with previous versions of Firefox, nor do I get that message when using Internet Explorer, so it's not a firewall issue.

Options>Advanced>Accessibility>uncheck Warn me when websites try to redirect or reload the page.

That fixed the problem, thanks. I'd looked at that box, but didn't realize that was causing it. Really appreciate your help !
