To me, it's like advertising a dead horse. I have used opera from the nineties and for me as many others, it died after v12, when it sold out to google. Ever since, i have been using Vivaldi, a product that was made by angry opera developers. Most feature rich browser for power users
I am one of those who stopped using it after v12 as well. However, even with the Chrome engine, now I am starting to enjoy using it again. Vivaldi is higher ranked in my desktop browser usage pattern as well. ;) At last, if you are looking for "most feature rich browser" you definitely need to try Maxthon.
