Tab Islands is a browser feature that automatically groups related tabs based on user activity, context, or websites visited. This clustering helps users manage multiple open tabs more efficiently and reduces clutter, making it easier to switch between tasks. From a cybersecurity perspective, Tab Islands can help isolate browsing sessions, limit cross-site tracking, and minimize the risk of accidental data leaks between unrelated sites. By keeping related tabs together and separating them from others, users can better control their workflow and enhance privacy. This feature is particularly useful for users who handle sensitive information or multitask across different projects.
