Hello Opera GX Team,

I would like to suggest a new feature that allows users to enter fullscreen mode on any website, even if the site itself does not provide a fullscreen button or native fullscreen support. This browser-level fullscreen toggle would enable users to immerse themselves fully in content such as videos, games, or reading material without distractions.

Key points of the feature:

A dedicated fullscreen button or keyboard shortcut in Opera GX to force fullscreen mode on the current tab.
Minimal browser controls visible or accessible in fullscreen for easy exit.
Optional settings to enable automatic fullscreen on specific sites or manual toggling.
This feature would greatly enhance user experience by providing consistent fullscreen functionality across all websites, regardless of their design.

Thank you for considering this suggestion!

Best regards,
KitKat
