Opera has experienced a 66% growth in monthly active users on Android in the UK and a 40% increase in the US year-over-year during the second quarter. This growth is attributed to features like a free unlimited VPN, an integrated ad blocker, and advanced AI tools, which are not provided by Google Chrome. Additionally, Opera's user base in Europe has also been rising, aided by the European Union's Digital Markets Act. Despite Chrome being the default browser on most Android devices, more users are exploring alternatives like Opera.
