A few words of thanks would be greatly appreciated.

Opera - Block Content

Upon browsing on the web, it may happens that you find yourself on a particular website with unsuitable contents and you don't want let your children to have access to the latter.

There's an easy way on Opera.

Once the webpage is opened, right click on a blank area and select the "Block content" option.

The website will be added to a "blacklist" accessible via:
Menu Button> Settings> Preferences> Advanced tab > Content Section > Blocked content interface.
