Firefox 56 with Ublock origin , yahoo home page

Just recently using Firefox version 56 with U block origin and yahoo home page there is a blank white space I guess where a ad is but U block origin is having trouble blocking it, if you refresh a few times blank white space goes away but comes back after re opening browser, I tried different browsers and disable all addons , and refresh firefox and different computers , the white blank space still appears , thoughts or suggestions ? not sure what else to try ?
