I&#x27;ll argue there was a later screw-up on the desktop browser (and really mobile too): Unite sucked resources from much for a long while, failure to tackle some of the technical debt (things that manifested itself such as the integer maths used for percentage values in CSS, contrary to every other browser out there, and that went unchanged as layouts became increasingly complex and the web relied ever more heavily on CSS), and in later years general lack of investment (while Opera was posting record profits on a quarterly basis) in Presto leading it to fall further and further behind the competition causing ever worsening site-compatibility issues.
