SEC_ERROR_UNKNOWN_ISSUER when https in Firefox

When you connect to https website in Firrefox, you may get an error: you connection is not secure and SEC_ERROR_UNKNOWN_ISSUER error.

This is due to that Firefox background ssl certificate process is not updated. We can remove temporary Firefox storage to fix the problem. The process is as following:
1) Click Any folder in Windows
2) Click Tool->View at top menu of the folder.
 3)  Check "Show hidden files, folder and drive" checkbox
4) Go to C:\Users, click your user name
 5) Backup Firefox bookmark
6) Go to AppData\Local\Mozilla, remove Firefox folder
7) Go to AppData\Roaming\Mozilla, remove Firefox folder
 8) If  folder AppData\LocalLow\Mozilla exsits, go to AppData\LocalLow\Mozilla and remove Firefox folder.

Make bootstrap Modal dialog draggable, move up and change header/footer style

I have Modal code:

<!-- Universal Modal -->
<div class="modal fade" id="universalModal"  style="margin-top:-150px;" tabindex="-1" role="dialog" aria-labelledby="universalModalLabel" aria-hidden="true">
  <div class="modal-dialog" style="width:1000px;">                                    
    <div class="modal-content">
      <form role="form" id="universalModalForm">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only"> Close</span></button>
          <h4 class="modal-title" id="universalModalLabel"><span class="glyphicon glyphicon-pencil"></span> Edit<span class="modal-title">.model-title</span></h4>
        <div class="alert alert-danger fade in" id="universalModal-alert" style="display: none;">
          <span class="alert-body"></span>
        <div class="modal-body">.modal-body</div>
        <div class="modal-footer">
          <input type="hidden" id='stakeholder_id' name='stakeholder_id'>
          <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
          <button type="submit" class="btn btn-primary" id="submitBtn"></button>

<!-- End Universal Modal -->
 1) To move  bootstrap Modal dialog up, I used style="margin-top:-150px;" for my id in top div including modal class.
2) To make   bootstrap Modal dialog draggable via modal header, body and footer
                $('#universalModal .modal-dialog').draggable({
                  handle: ".modal-header, .modal-body, .modal-footer"

3) To change header and footer style
  .modal-header  {
      background-color: #5cb85c;
      color:white !important;
      text-align: center;
      font-size: 20px;
  .modal-footer {
      background-color: #5cb85c;;

Microsoft Family Windows 10 Parental Controls Screen time not working and swtich to Norton family

I have windows 8,  later upgraded to  Windows 10. Parental Controls Screen time is not working anymore after upgrading. First screen time does not show correctly.  My hourly rule and block all days are not working.  I checked the solution by google.   was told that On the Start screen, right click and the find run and click, and  type C:\ProgramData\Microsoft\Windows\Parental Controls and press Enter. 
 Delete all contents of the Parental Controls folder.  "
This will delete any corrupt files. Your settings will be downloaded again from the next time you sign in."
I did find settings.bin, but inside almost empty, only "{}".

I think there is a problem in Microsoft family Windows 10 parental control. Finally I switched to Norton Family.  Norton Family has  same feature Microsoft family has, but has more, although I need to pay small money each year.

Norton family premier link:

There is 30 days free trial. I am quite satisfied Norton family during trial.
