This might not be the entire issue, but since you are getting a blank page, please make sure the redirect block is turned off: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. ''More info on about:config:'' [[Configuration Editor for Firefox]]. ''The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future. Since we are restoring a default setting, I feel comfortable mentioning it.'' (2) In the search box in the page, type or paste '''access''' and pause while the list is filtered (3) If the '''accessibility.blockautorefresh''' preference has a value of true, double-click it to restore the default value of false Any difference?
