I, too, am a Firefox convert, or at least trying to convert. I simply can't get used to a browser that does not have a dedicated search box. They are Far too useful and have become second-nature for me while researching and doing homework. So, if Opera is going the dark route of following Chrome and Edge, and dropping the dedicated search box, then I'll have no choice but to stick with Firefox/Waterfox. I'm hoping, it was just an oversight in GX and they bring back the option for enabling the dedicated search box.
