Opera browser advanced settings –which used to exist at the bottom of the settings page in Browser section (check the second screenshot) and offers additional options (when enabled) to control hardware acceleration or change the number of columns that display on speed dial — has been moved to the sidebar in Opera 42. This is a significant change. From version 42 onwards, you need to look at the bottom of the Settings sidebar to see to enable ‘Show Advanced Settings’.
