Comment 1 for bug 1691243

I had the same concern too when I first started testing the web client, but I think this is actually a browser issue and not an Evergreen issue. I added a paragraph to the web client docs to talk about this a bit - http://docs.evergreen-ils.org/2.12/_tab_browser_based_tab_buttons_and_keyboard_shortcuts.html.

The problem is modern browser don't open new tabs in home pages anymore, but both Firefox and Chrome do have add-ons that force this behavior.
