    I can't see any problem there.

    Suggest - backup profile to a directory outside of Program Files or Appdata - use a folder on your desktop or something.

    Download Hekasoft Backup & Restore 0.81


    You should really also manually make a backup copy of your FF profile:



    1. Press [Windows key+R] on the keyboard. A Run dialog will open.
    2. Type in:
      %APPDATA%\Mozilla\Firefox\Profiles\


    Or else navigate to:

    C:\Users\<Windows login/user name>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile folder>.

    backup these two: (Profiles folder and Profiles.ini file) to a folder on your desktop.
    AppData\Roaming\Mozilla\Firefox\Profiles\
    AppData\Roaming\Mozilla\Firefox\Profiles.ini

    Export your bookmarks as Html file and save the file somewhere.

    Get a copy of GeekUninstaller and run it. https://geekuninstaller.com

    Find Firefox in the list of programs and double click it.
    Choose yes when deleting profile data.
    Allow it to scan for leftovers.
    From the results list delete everything directly related to the Firefox Program installation or application data.

    Reboot when finished.

    Run Cccleaner if you've got a copy. Check here for Firefox leftovers (important) and delete if found:

    C:\Program Files\Mozilla Firefox
    C:\Program Files (x86)\Mozilla Firefox
    Press the [Windows key+R] to open a Run dialog, type in %APPDATA%\Mozilla\ and click OK to open the Mozilla folder, then delete the Firefox folder if found.

    Reboot.

    Download a fresh copy of firefox and install it. Import your bookmarks. Re-add your extensions manually.

    Dont you think "pavel.sherbakov@gmail.com" added in the file in the section of ff addon is suspicious?

    Also google is my default search engine. I see several references to 'bing.' Again dont you think thats suspicious also?

    Do you think I should delete all these entries or what do you suggest?

    The email indicates that you have an FVD Media Inc extension installed. The email belongs to the developer.

    Bing can be removed - it's not suspicious.

    Type about:preferences#search in the address bar. Make sure that bing is non-default then in the search engine list highlight bing and remove.

    I would still suggest clean installing firefox and that means removing leftovers after uninstall.

    If you like you could run:

    Wise JetSearch - Free Local File Search Tool for Windows

    In the search box type .xpi

    Try to find the .xpi relating to pavel_sherbakov_gmail_com and if found zip it and upload it here.
