[Privacy bug] The creating a bookmark in a private tab with VPN causes connection non through VPN

  • When you are in incognito mode (private tab in Opera) and use Opera "VPN" if you add a bookmark it causes connection non through VPN to this site for the image preview.

    It can be easy detected by DNS leaking. (You need only DNSQuerySniffer)

    1. Run DNSQuerySniffer (as Administrator)
    2. Opera a private tab
    3. Open any site
    4. Bookmark the tab
    5. See that the site domain was resolved non through VPN so you see DNS resolve in DNSQuerySniffer.

    It's a bug. PRIVACY BUG.

    (Just for SEO: security bug)

  • Sad to say, but it is not a new bug. Opera 58 has it too.

  • The related topics:

    Bookmarking a new site (which you din’t visit in non-incognito mode before), bookmarks will not have a favorite icon.

    [2]
    The creepy bookmark warning when you create a bookmarks and have at least one incognito tab.
    Better change the text what creating a bookmark in incognito mode will cause the privacy leak.

    ....

    The additional:
    The private tab is with enabled "VPN".
    The non-private tab (window) is without enabled "VPN".

    So, the problem is obvious – сreating of a bookmark happens in common window even you add it in an incognito tab.

  • You know that search engines circumvent the VPN by default in Opera?

    Ridiculous default of course, that goes for much more in Opera.
    [The most serious thing is that Opera starts by default as a scheduled task to check for updates.
    In practice, this means that every time Windows Opera starts up, it always checks automatically for updates.
    How you dare to call yourself a privacy browser remains a mystery to me.
    By the way, Brave and I think Chrome (you can find it anywhere in Windows where you don't want it anyway) as well.
    Actually it's a pity Opera doesn't have these things in order, in itself it's a pretty nice browser.]

    I don't think that is a problem.

    • It can be easily found in the options (It's not a hidden option).
    • It can be disabled (It's the important part).
    • It has benefits - you get a relevant search result (for based on your IP location) and no captcha.

    I also want an option to easily disable auto-updates, for example, future Manifest V3 can break a lot of extensions that get you better privacy (not only ads blockers).
