''deltabravo [[#question-1079406|said]]'' <blockquote>I've tried installing the plugin from http://mycroftproject.com/ but the plugins are useless!! </blockquote> What do you mean by useless? Did the new plugin show up on the search bar as the last icon? Does it not work if you click it to send a query to it?

Is something holding you back from upgrading to Firefox 40? Please let us know so we can suggest solutions or workarounds. ''Note: If you are concerned about Video Downloadhelper, there is an update that fixes the problems it had with Firefox 36.''
