After a period of beta testing, version 120 of the Opera browser is now being rolled out to the public. The biggest piece of news in this particular update is a new built-in translation feature with support for over 40 languages, and the browser is now based on Chromium 135.
To protect privacy, the new Translator feature doesn’t pass any information on to third parties, and the translation itself is processed using AI (in partnership with Lingvanex) on Opera’s European-based servers.
Other improvements in Opera 120 include improved password management, enhancements to Split Screen mode, refinements to Tab Islands, a new Miniplayer for videos, and VPN Pro.
Lastly, Opera 120 includes a fix for a serious zero-day vulnerability (labeled CVE-2025-6554) in the V8 JavaScript engine. For more details, check out the full changelog for Opera version 120.
