@blackbird71 Opera has version called "Opera Neon" it would be great if it was working on Presto engine, cause other than Youtube starting to crack down on adblockers there are more reasons to start digging up presto engine, or at least implement it's features to default browser

Neon is also built upon the Blink rendering engine, as are all chromium-based browsers. All browsers (Blink or otherwise) must convert the data packets received from a website's server and convert (aka: render) them accurately into a screen display on the visiting computer that replicates the images and functionality that the website designers intended.

There are multiple ways to render a website's code, not all of them equally efficient or easy to maintain - and not all equally able to withstand idiosyncrasies continually being inserted into particular website coding techniques.

Consequently, different rendering engines may not always display a given website in the same way as one another or as the site designers intended (especially if they designed and tested the website with a particular rendering engine design in mind). As a result, maintaining a "minor" rendering engine design for maximum website compatibility over time quickly becomes a huge and costly effort.

Opera fought that battle constantly in its early years, increasingly with only mixed success. When sites aren't rendered properly, complaints flood the support lines of both the browser makers and the site designers. For that reason, Opera (and others) have elected to go with an existing major rendering engine design (Blink) developed and continually maintained by the Chromium Consortium - which brings us to now.

At this point, there's virtually no chance of going back to the pre-Blink days or its designs... the costs would simply be too great, and too many technological changes have since occurred.

"Presto was the browser engine of the Opera web browser from the release of Opera 7 on 28 January 2003, until the release of Opera 15 on 2 July 2013, at which time Opera switched to using the Blink engine".

IMO, good move, ie., time to move on.
