Browser for macOS
Opera Browser for macOS is no different than Opera Browser for Windows. It’s also a desktop browser that maximizes your privacy, content enjoyment, and productivity. In our browsers for computers, you can use a wide range of add-ons to personalize your browser.
Browser for Linux
Just like the browsers for Windows and macOS, the browser for Linux is a desktop browser and works on the same principles. In these browsers, you can also use Chrome extensions for even better personalization of your Opera browser.
