Extensions, bookmarks, left sidebar DEAD AND GONE after computer shutdown

  • Hello,

    After rebooting my laptop (which shut down probably because of low battery), I found out that Opera has deleted all my extensions and bookmarks, and also the fancy sidebar is no longer present.

    The history IS NOT deleted, and I DID NOT use any 'cleaning' software. Fortunately I can copy the bookmarks from another browser, but I've spent hours searching for extensions and picking those most suitable for me so I would be very frustrated to find out they're gone for good.

    Running Opera 49.0.2725.47 on Windows 10.

    Thanks for any help.

  • Any windows update during that happening?
    A user reported that Windows create him another user, then "all disappeared".

    Check your computer users.

    Look at:

    • Opera Help > Find solutions.

    And locate your profile folder, check there if there is another Data folder or .bak files.
    Look for an extensions folder and check if something there, look at their dates if any.
