Major Privacy Problem

  • Well, under Clear browsing data I have everything ticked and choose to delete from 'the beginning of time'. Can't do much more than that. I also use the extension Disconnect to block trackers. The irony with this extension (and most if not all extensions), it needs permission to access my browsing data! I'm sure this is just so it can monitor and block trackers but, still, this is why I don't run lots of extensions (Opera eliminates the need as it has native features other browsers don't). The Click&Clean extension you use (I assume it's this one) will be accessing your browsing data too. I used that extension for a while but, for my needs, it didn't really provide more than ctrl+shift+del does. Btw, no master function to delete all data has existed in Opera (or other browsers) as I would have used it. I believe, to the best of my knowledge, Opera is functioning the way it always has.

  • @Cozza,
    It's not about the settings in the browser, they're all set correctly for me, it's not about what cookies or offline data is needed.
    I'm concerned with security, protecting our privacy.

    I have selected the option "Delete local data when closing the browser", as well as the option "Since installation" under "Clean Browser History"

    BUT:

    If you do not close the browser, then all entries of the "Offline Data" and "Cookies" are retained. The data appears to be deleted, but not the entries. Everyone can then see which websites you have visited.

    This is a problem when several people are working on a computer. If you forget to close the browser, the next one can see your browsing history (the entries), and that's a "no go"!

    In order to preserve the privacy, it is sometimes necessary to delete the browsing history, otherwise your cookies and other data will be read out from other websites and you will be profiled by yourself. Most cookies are used to spy on you, not to make your life easier.

    It is also not very convenient to close the browser every time to get rid of the garbage.

    @blackbird: You have understood me. In Opera 47 that was not a problem, because you have not seen these entries, in any version before Opera 48.
    It may be that the entries are left over, but we could not see them ... (internal database)

    I hope the Opera developer team corrects the problem with the visible entries. All data must be deleted if you use "Clean Browser History" (depending on the settings!) If I select everything, then everything must be deleted; not only the data, but also the entries.

    Why else do you use "Clean Browser History"?

  • So, you're basically saying there's a bug, and the bug is that the "clear browsing data" function doesn't flush the local storage entries from the "All cookies and site data" dialog?

    (Where the entries only get flushed/removed on exit of the browser, either because the flushing is delayed till exit or there is no flushing and they'e just no longer there on startup because the data and entries are gone from the files.)

    To me, it sounds like a simple UI issue.

  • @burnout426
    Maybe just a bug of the UI, maybe a real problem !?

    Anyone can check the bug itself:
    Clean your Browser History and close Opera. Now restart Opera and visit some websites, such as a major online retailer, a well-known daily newspaper, and the page of a computer magazine (or something else)

    Now clear the browsing history (maximum privacy settings); now look at the settings under "Cookie Management", here you can see all the cookies and offline data you left while surfing,
    => press "delete everything" and "finish" and all entries will be deleted;
    Close the window of the "Cookie Management" and open it again immediately => and all entries are back ... and that is not acceptable.

    The only way to delete the entries is to close the browser => that is completely unnecessary and makes no sense.

  • I've just discovered that if you want privacy, Opera is not the browser for you.

  • If you want privacy, you use a private window.

    Yes I can confirm. To me, it's a bug that should be fixed.

  • I can confirm using Firefox, deleting browsing data doesn't remove all cookies either (I have found other browsers to behave the same). However when I manually removed them, they seemed to stay removed. Although manually removing worked, it is a huge faff and not something I would want to have to do every browsing session. @bitrat have you reported this to Opera? I don't think they read the Opera Forums.

    If I get you correctly, you are saying unless you close the browser, your local cookie history would be available to anyone who knows where to find them? Is that the main point of your argument? Personally, not an issue for me as I always delete the data and close the browser after use. Also, what if someone closes the browser but forgets/doesn't know to clear the data? Local cookies would go (if selected in privacy options) but everything else would remain, including browser history. Personally I prefer the Firefox approach that allows all data to be automatically deleted when closing the browser as having to delete data every time before closing is quite annoying.

    I think he's saying that the data details get deleted, but not the entry titles for each site visited, He wrote: "...If you do not close the browser, then all entries of the "Offline Data" and "Cookies" are retained. The data appears to be deleted, but not the entries. Everyone can then see which websites you have visited."

  • If you are sharing a computer with others without each one having its own user to access that computer then your privacy will always be zero.

  • @blackbird71 Eh? Looking at the cookies, local cookies are the only ones that remain after clearing data. They tell you the site visited and time visited. All other cookies are deleted. After browsing, simply pressing ctrl+shift+del (and deleting data) followed by ctrl+shift+x to close will get rid of all browsing data (and remember to sign out if on a shared PC). Whether it's a bug or not, it's still that simple to do and easy to remember. If cookies remained even after closing the browser, which they don't, then we'd have a major security flaw.

  • @Cozza
    Yes, I sent the bug to the Dev-Team.

    @leocg / @Cozza
    There are many situations in which you need to share a PC for Internet access, for example, if the network administrator does not allow freelancers to access the corporate network, or in a large family, or in a shared flat with only one PC. So there are so many such situations ... We can discuss that for an infinite amount of time, but that will not fix the bug.

    Why do the cookies and offline entries remain visible after deletion? I am not sure if this is just an error of the GUI, or if the data can still be found in a cache or a database, which can be read by a website !?

    A good browser also has to be fault-tolerant ...

    Thanks for your contributions.

    Thanks blackbird71 and burnout426, we are on the same track.
    Let's see what the Opera Dev-Team does.

  • Thought you all might like to know, I've recently been testing Opera Developer v50 and as far as I can see, ALL cookies are being deleted when either using 'Clear browsing data' or manually deleting them without needing to close the browser. Please run your own tests to confirm. Perhaps Opera took notice of the bug report (I sent one too).

  • Bugs DNAWIZ-22081 and DNAWIZ-21841 have been filed about this issue. They have not been resolved. However, I also tested in the latest Opera Developer (Opera 50) and I couldn't reproduce the problem. Can anyone else confirm that it doesn't have in Opera 50?

  • @cozza
    @burnout426

    I have just installed the latest beta version.
    In Opera DEV-BETA 50.0.2762.4 64-Bit the Bug is fixed.
    Let's hope that it stays that way in the stable version.

    Special thanks to the Opera DEV-TEAM,
    and thanks to all interested in the forum.
