An update from about a year ago changed the search tab features, for the worse. But there was a work-around that reverted to the old way. https://support.mozilla.org/en-US/questions/1035129 And the old way is better: there is a helpful icon constantly displayed to show what site is searched at, and one is able to change the site searched at quickly. Plus, searching with the old way is quicker because instead of (in the updated way) clicking into the search field, moving to the keyboard to type your query, then grabbing the mouse again and clicking what search engine you want, the old way is click into the search pull down and click again to choose your site, then move to the keyboard type query and hit 'enter'. Less back-and-forth, you see. But most recently the work-around stopped working! Couldn't there be an option in the search preference pane to allow both ways to be available, rather than just one?
