  • Recently Opera has been running slowly and crashing/hanging. I accidentally discovered a new plug-in that doesn't show up on the official Opera browser plug-in list that can be accessed through Settings. The plugin appears to be from and I do not recall giving permission for its installation. In addition, it is not [yet] seen as malware by Norton 360. My file finding software found two files with the same name:; they are listed as located in my AppData\Roaming\Opera Stable\Local Storage\ directory. However, all the files in that directory are .localstorage or .localstorage-journal files and none of the names contain "plugin_netotiate". How do I uninstall this plugin? The files do not show up the list of programs generated by Windows/Control Panel/Programs and Features or in another uninstaller I use. Or, can I just delete the appropriate files in the Local Storage directory? If so, how can I tell which two files are the correct ones to delete? None of the file names in that directory have names that are recognizable. I have a Windows 7 Professional 64-bit SP1 system. Thank you.

  • I guess it's this beast -
    Unfortunately, Opera can load plugins from almost anywhere on your system, not just its own plugins folders.
    I would do a registry search for "Netotiate" and that should hopefully reveal where its files are.
    The plugin file name probably begins with "np" (standing for "Netscape Plugin") if that's any help.

  • There is no plugin. There is a website called that is storing some data locally.

    Just add it to an exception, choose to block cookies and local storage from the page and then remove it from the "all cookies and site data" list.

  • Thank you davehawley and leocg. describes the new "marketing service" I found offered at I searched the registry and could not find a key with "netotiate" in the name. I then blocked cookies and local storage for,, and, all of which I found listed in Opera/Settings/Privacy and Security/All cookies and site data. Blocking all three seems to have worked. Thank you so much.
