I have already seen some suggested solutions to the problem of this extremely annoying Yahoo DNS error solutions page, but they involve going to the add-ons page of firefox and disabling various add-ons. The issue is that even when I try to go to the add-ons page I get immediately redirected to the Yahoo DNS solutions page again. I have cleared my browser history and cache, hoping it would help, but nothing. Extremely annoying as I never installed anything - it simply started after a Firefox upgrade. Any help much appreciated.
