Now that the Opera 50 web browser hit the streets with its anti-Bitcoin mining feature implemented in the built-in ad blocker, it’s time for the development team to focus their efforts on the next major release, Opera 51, which promises a 13% increase in browsing speed due to recent string matching algorithm improvements. The Opera 51.0.2830.0 developer update also adds imported bookmarks to the Bookmarks manager, thus making it a one-stop shop for all your bookmarks actions. Imported bookmarks are now displayed as a single folder along with the exported bookmarks, which are available from the expandable menu.
