Middle click on search suggestions in Search Bar does not switch to new tab

Question

I use profile option "When I open a link in a new tab, switch to it immediately" = yes (check marked)
Middle clicking on a search suggestion in the Search Bar does open a new tab but Firefox does not switch to it.
This feature used to work for many years until very recently.
Anybody have any ideas?

Answer 1

Did the problem start with the new search bar design in Firefox 34?
If you want to switch back to using the old bar, it's still hidden inside. Here's how you would do it:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box that appears above the list, type or paste '''search''' and pause while the list is filtered
(3) Double-click the '''browser.search.showOneOffButtons''' preference to switch it from true to false
This doesn't affect the current window, but each new window you open (Ctrl+n) will have the old Search bar.
I'm not sure when that will be phased out...
