Opera browser for developers - with built-in ad block

Opera browser is back with built-in ad block (in developer version only). Does it work? Well, at least both ads (there are only two of them) on my site https://sakarinkurssit.blogspot.fi were stripped off. Look at the pics below.

If you don't want to mess around with different ad block add-ons download Opera developer version. In addition, Opera promises to load web pages quicker than other browsers do.

Click Menu, Settings and you'll find option for ad block
