I also love this feature--if I can find the icon, that is. Problem with FF57 is that on the latest version of FF, I can't locate the icon. It used to be visible but not anymore. :( Bummed. Thoughts?
I use this add-on ALL THE TIME. Would love a global option to have this add-on open the tab in the background (and an add-on that did the same for Bing/Google.)
