Easy, context-based tab grouping for effortless browsing.


With Tab Islands, Opera has reimagined tab functionality to give you more space and focused browsing. Tabs can be easily arranged into separate groups, or islands, which can be collapsed or expanded. When you open a new tab at the top of your browser, it begins a new group. However, tabs opened within a group stay connected, so that related tabs can be found easily. You can also drag and drop tabs between islands, and manage entire groups at once.

Tab Islands is a simple and intuitive way to keep your browsing sessions separate, without being overwhelmed by tabs. This feature, along with Workspaces on the top of your sidebar, provides convenient ways to keep your browsing sessions separate while keeping your tabs organized. Try it out to see how much simpler browsing can be.

Dynamic interface

Opera One’s modular design makes room for new features and integrated AI tools as they become available.

The UI has been reimagined with a modular design that adapts as features are added or tabs are opened.

In the sidebar, elements are dynamically adjusted as others are added, making space for more cutting-edge AI integrations as they become available. And as extensions become more and more relevant with new generative AI features, Opera One groups them in a collapsable module in the address bar, simplifying the space while retaining quick access.

Functionally, Opera One has been reengineered with a new technology stack which ensures that animations run smoothly without interruption.

The modern web is active and animated, and past attempts to reflect this dynamic environment in browsers have resulted in lag and stuttering. Opera One has resolved this issue by introducing a separate compositor thread that paints the active elements in the browser. By using layer-based animations that run entirely in the compositor thread, rather than the UI thread, animations continue running even if UI processes are interrupted.
