Opera is adding integrated ad blocker to its browsers on both Windows PCs as well as to mobile, starting with Opera Mini browser for Android. Last month, the company also announced a free VPN bundled with its desktop browser.

"Opera is the first browser company to offer an native ad blocker across devices. We do this because we want to provide people with the fastest browsers in the market. Our speed test shows that online ads slow down the browsing experience. Now, with Opera, you can browse a lot faster than, for example, in Chrome," said Lars Boilesen, CEO, Opera.

The company claimed that with native ad-blocking, the new Opera for computers speeds up page loading by as much as 89% compared to browsing without ad blocking.
