Hello from Pluto
"Opera's browser is very well-regarded" - what planet are you writing from? I can't believe I just read that! FMD, 99% of punters quite correctly regard Opera's browser as a no-account fifth-rate clone of Chrome with added major flaws and nothing much anyone can think of to recommend it.
Opera's brower used to be very well-regarded - indeed many good judges regarded it as best-of-breed and even its detractors granted that it pioneered all sorts of features which the other browsers eventually copied and which are now regarded as obvious standards.But that was years ago before Opera Inc inexplicably abandoned its one great product along with its loyal users and chose instead to shoot itself in the head. Nobody knows why.
(Yes, yes, Pluto isn't really a planet anymore. That's my point, really.)
