The latest version of Opera, which is still a useful alternative to Firefox and Chrome, sports an improved (and faster) ad blocker.

The new ad blocker now provides protection against cryptojacking, where a web site will attempt to use your browser (and your computer) for mining cryptocurrency.

With Opera 52, you can now select multiple tabs, and perform various operations on all of the selected tabs, including copying the related URLs to the clipboard with a single command.

The release notes and change log for Opera 52 provide additional details.
