Opera reverting to defaults when closed

  • Hello, I am running Opera 38.0.2220.31 on Windows 10 Pro version 10.0.10586 Build 10586.

    Whenever I close the browser, all settings, extensions, logged in sessions, cookies are lost and reloaded as defaults when I open Opera back again. The current browsing session, however, is saved and restored correctly.

    Looking at the ...\Opera Stable\Extensions\ folder, I can see folders for extensions being created when I install them, but ignored when I restart Opera and deleted a few seconds afterwards.

    If I manually delete the user profile folder, then data is kept if I restart the browser, but lost if I launch it after a system reboot.

    What could be causing this? It started doing it out of the blue and I don't recall changing anything reasonably relevant on my system (like, say, .NET assemblies or whatnot).

  • For the record, I switched to Opera Developer 40.0.2273.0 and the problem went away. It's mighty odd, though.

  • Probably a broken profile? Or maybe something preventing Opera to write in the profile folder for the stable version?
