Quick Start & Pro Tips

Activating the Built-in VPN for Enhanced Privacy

Open Opera One settings by clicking the O menu icon (top-left) and selecting Settings, or by pressing Alt+P (Windows/Linux) / Opera menu > Preferences (Mac).
In the left sidebar, navigate to Privacy & security.
Scroll down to the VPN section and toggle Enable VPN on.
A blue VPN badge will appear in the address bar, allowing you to turn it on/off and select a virtual location.

Explanation: Enabling the built-in VPN encrypts your internet traffic and masks your IP address, significantly enhancing your online privacy and security, especially when using public Wi-Fi networks.

Customizing the Sidebar for Streamlined Productivity

Click the three-dot icon located at the bottom of the sidebar to open Sidebar settings.
From the list, check or uncheck desired apps such as WhatsApp, Instagram, Twitter, ChatGPT, or Google Calendar to add or remove them from your sidebar.
You can also reorder the integrated tools and messengers by dragging and dropping them to your preferred positions within the sidebar.

Explanation: The customizable sidebar provides quick, one-click access to essential messengers, AI tools, and other utilities, streamlining your workflow and reducing the need to switch between multiple applications or tabs.

Mastering Tab Islands for Organized Browsing Sessions

When opening related tabs (e.g., for a research project or shopping spree), Opera One will automatically group them into a distinct Tab Island.
To manually create a Tab Island, simply drag one tab onto another tab.
Hover over the island’s handle (the colored bar) to easily collapse or expand the group, or to customize its name and color for better organization and quick identification.

Explanation: Tab Islands revolutionize tab management by intelligently grouping related tabs, helping you maintain focus and effortlessly navigate complex browsing sessions, preventing tab clutter and improving overall efficiency.
