Site not working in Opera? Check the built-in ad blocker

Opera (and Opera GX) can block ads and trackers on its own, without any extension. When it’s on, it can take embedded players, comment sections or a site’s own scripts with it.

Updated November 2026. Menus move around between versions: if a label is a little different, look for the closest match.

Quick test

1. Click the shield icon at the right of the address bar (it appears when Opera has blocked something).
2. Turn blocking off for this site.
3. Reload. If the page works, Opera’s blocker was the cause.

Fix it

• For this site only: leaving blocking off from the shield icon adds the site to Opera’s exceptions.
• Review or undo exceptions: Settings → Privacy protection, next to the ad-blocking and tracker-blocking switches, under Manage exceptions.
• Ad blocking and tracker blocking are separate switches. If only one breaks the site, keep the other on.

Good to know

• Opera reports these blocks the same way extensions do. If you also use a blocker extension, pause it too when testing.
• Opera’s built-in VPN changes your network path. If a site won’t load at all, try with the VPN off.
