Cookie dialog blocking is not fool-proof, but Opera said it successfully tested the feature with 15,000 websites.
The new version 48 of the app has two more neat features. If your phone is on Android 7.1 Nougat and above, you can create QR scanning, search or browsing tab shortcut directly on the Home Screen. Long tap on the Opera app icon and just select New Tab from the 3D menu.
The new text wrap feature was tested in Beta and finally makes it to the final rollout. Just go to Text options, click Text Wrap and select your desired size of letters.
