Opera Software has released Opera 52 as the latest stable version of their software. This version includes a faster ad blocker, new tab features, and new animations for error pages. According to Opera Software, Opera 52’s ad blocking is significantly faster than both Chrome and Opera 51 based on a test that was performed last month. Users can select multiple tabs by holding down Ctrl while clicking on each desired tab ( + click for Mac users) and clicking on a tab will select all other tabs to its right.
