Opera Presto Source Code Leaks Online (bleepingcomputer.com)

Catalin Cimpanu, writing for BleepingComputer: An unknown third-party has leaked the source code of the old Opera Presto browser engine on GitHub, and later on Bitbucket, two services for hosting and sharing source code online. Opera Presto is the layout engine at the heart of the old Opera browser. Opera Software used Presto between Opera 7 and Opera 14 and replaced Presto with Blink, Chrome's layout engine, in Opera 15, released in May 2013. Despite its removal from the company's main product, Opera engineers continued to use Opera Presto for the Opera Mini and Opera Mobile browsers. According to timestamps, the Opera Presto source code was first uploaded on GitHub but was taken down last Friday, on January 13, after Opera's lawyers filed a DMCA request.

    I think it may have influenced my browser choice.

    Opera less than/equal v12 was and still is a superior browser for speed/efficiency.. I still use Opera v10.10 as my main browser today, loading pages in others only when there are display problems. If Opera Presto ever did go open source it could quickly become a real threat to the proprietary junk chrome and others are turning out.

    Best thing about Legacy Opera is it gives control over individual pages/domains; options scripts/cookies/css/content blocking... Nothing for the average moron but oh baby, nothing like it for techs.

    Where can I find this source code now plz!

  3. Opera Mini is Webcore, not Presto by emil · · Score: 3, Insightful

    If you set the "data savings" option down from extreme to high in the settings menu, the scanner at ssllabs.com will report Webkit, not Presto. The Webkit version will be whatever is included on your device (Webcore). If you are running KitKat or Jellybean, you will see lots and lots of security problems with your Webcore, since they date from the end of the XP era, and haven't been updated since.

    I believe that Presto would be installed at Opera's corporate systems, and it would feed a compressed stream to the Webkit used by Opera Mini.

    Opera Mini could not be so small and include both a complete rendering engine and links to Webcore. They essentially cheated.

    Ironically enough, it could be more true since Russians tend towards Opera for some weird reason.

    It has decent language support, and is not American.
    Russians have (possibly for good reasons) as much distrust of American companies as Americans have of Russian companies.

  6. Why dont they open source by Eravnrekaree · · Score: 4, Insightful

    Since they have mostly given up on Presto and no longer develop it, why not open source it? I dont get why they would freak out over a source code leak, since they no longer support or provide a product based on it. It makes no sense

  7. 3rd party code by emil · · Score: 4, Interesting

    One common reason is 3rd party code, which they may have licensed and do not control or own.

    Alternately, the code may still be seen internally as useful, which it is with Opera Mini. It is still used to generate revenue, and may contain what Opera considers to be trade secrets that give them an advantage over a competitor (i.e. Amazon Silk).
