Opera 52 is out! It is based on Chromium 65 (hence it inherits its changes) and comes with an improved ad blocker and more fun features that we'll summarize in this post for you. We already installed it on our cross-browser testing platform so you can try them out there as well.

New Features in Opera 52
- Faster ad blocker
Opera cares for our protection. Its ad blocker was implemented over two years ago and earlier this year it added security against cryptojacking with the NoCoin Cryptocurrency Mining Protection feature. Opera now has faster ad blocker that outperformed not only its predecessor, but also Google Chrome's ad blocking contender. To a huge extent Opera's string matching algorithms can get the credit for that. The whole optimization resulted in faster page loading time.
- Select multiple tabs and copy page addresses
Rarely someone browses with just one tab opened. Opera 52 enhances further the way users can interact with their tabs, especially executing actions on multiple tabs at once. Another thing that worths mentioning is the new close tab shortcut. How to select multiple tabs at once? Maybe you can guess it yourself. Same way you select multiple icons at once on your desktop - just press control and select multiple tabs and you can then perform actions on all of them at once. Holding down Shift and clicking on a tab will select all other tabs to its right. Tabs context menu has a new feature called Copy page address(es). It is an action to be performed on multiple tabs. As the name suggests, this will copy all the page's addresses to the clipboard for easily pasting afterwards. And the last, but not the least: Tabs can be closed by holding Alt while clicking it.
- New animations
Error pages are boring. All you see is a problem. Opera 52 introduces a whole new set of cool animations to take place in certain errors. For example, on the error "Site can't be reached" you will see this animation:
There are many other animations and we'll leave them as a surprise to you. Though we hope that you won't see them soon.
