Helium Backup browser extension

Overview

inWebo Helium Backup is a browser extension developed by inWebo Technologies. It allows the user to keep his inWebo browser enrollment token (inWebo Helium, mAccessWeb and inWebo Virtual Authenticator) in the event of an unintentional or intentional deletion of browser site data (e.g. clearing your history).

To be noted

If you allow this extension in Private Browsing mode, you will be able to use Helium and Virtual Authenticator in this context as well.

inWebo Helium Backup can be used only with inWebo products.

How to detect the installation of the inWebo Helium Backup extension in your web pages

inWebo provides a javascript you may add to your pages to detect if a user has installed the backup extension.

To add the script, simply add the following line in the header of your page:

<script type="text/javascript" src="https://www.myinwebo.com/common/js/iwhbdetect.js"></script>

Then call the function iwhbdetect to detect the extension:

<script type="text/javascript">
   function handleDetect(res) {
     if (res == "iwOK") {
         // Helium Backup is detected, user is good to go
     }
     if (res == "iwNOK") {
         // Helium Backup is not detected, you should ask the user to install it
     }
   }
 
   // Launch function iwhbdetect on the event of your choice. Here: window.onload
   window.onload = function() {
     iwhbdetect(handleDetect);
   };      
</script>

All browsers : HTML Test Page to check your local Storage configuration

You can use this test page to test if your browser is correctly configured for Helium/VA persistence. Simply copy-paste this code in a text editor and save it as HTML, 'LocalStorageCheckPersistence.html' for example. Now upload the page on a web-server, and view it with your browser.

<HTML>
   <head>
        <meta charset="utf-8" />
        <title>Helium&VA LocalStorage Check</title>
 		<script type="text/javascript">
			// Test the LocalStorage Availablity and Persistence
			var storage;
			try {
		  		FirstLaunch=(storage = window.localStorage).getItem('FirstExec');
		  		if (FirstLaunch == 'yes') {
			  		console.log ('LocalStorage Persistence is OK');
			  		alert ('LocalStorage Persistence is OK');
			  		document.write ("<H1><font color='green'>This browser is ready for InWebo Helium or Virtual Authenticator<BR>");
			  		storage.removeItem('FirstExec');
		  		}
		  		else 
		  		{
					(storage = window.localStorage).setItem('FirstExec', 'yes');
					alert ("Please Close and Reopen the browser on THIS page. \r\n If this message is still displayed after reopening, Cookies persistence is **DISABLED**. 	Helium/VA won't work properly.");
					document.write ("<H1>Please Close and Reopen the browser on THIS page<BR> <H2> <font color='red'>If this message is still displayed after reopening, Cookies persistence is **DISABLED**. <BR>Helium/VA won't work properly</font><BR>") ;
					document.write ("See <a href='our'>our'>http://developer.inwebo.com/docs/user_guides:heliumbackup'>our developer website</a> for further explanation");
		  		}
 
 
			} 
			catch (exception) {
				console.log ('***PROBLEM*** LocalStorage Disabled. InWebo Helium/VA *will not* work');
				alert ('***PROBLEM*** LocalStorage Disabled. InWebo Helium/VA *will not* work');
				document.write ("<H1>InWebo Helium/VA won't work until you enable the LocalStorage<BR>");
				document.write ("<H2>See <a href='our'>our'>http://developer.inwebo.com/docs/user_guides:heliumbackup'>our developer website</a> for further explanation");

inWebo Helium Backup Troubleshooting

In this section, we assume that the inWebo Service-side configuration is correct. Only potential browser configuration errors that prevent Helium/VA/mAccessWeb/Helium backup from running are listed here. Please ensure that all the specific browser requirements are fulfilled as detailed in the sections above.

Internet Explorer

Problem: Helium/VA is not displayed

Under certain circumstances, some Internet Explorer parameters cannot be changed by you or by your administrators. If Helium/VA is not displayed on your computer, please check the following points :

• Please verify the security zones configuration corresponds to "Internet Explorer Requirements" in the "Browser requirements and configuration" section of this page. 
  To check your configuration :

  • on your login page where Helium/VA is supposed to be displayed, right click in the page (or use 'file' menu) and select 'properties'.

  • Verify the value displayed for 'Zone'. It should be:

• The parameter 'Active Scripting', sometimes called 'Scripts ASP' found under your zone configuration is mandatory for Helium/VA to be loaded in IE.

  • Determine the current zone for your page as explained above, then open the 'Internet Options' window, go to the 'Security' tab, and select the correct zone before you click the 'Custom level…' button.

  • Verify that the parameter 'Active Scripting' (or 'Scripts ASP') near the end of the options list is set to 'Enable'. If not, you must enable it for Helium/VA to work.

Problem: Helium Backup does not maintain the browser enrollment

Helium Backup ensures Helium/VA persistence by permanently maintaining a copy of the local storage data for the domain 'ult-inwebo.com'. If the local storage is cleaned, Helium Backup automatically recreates the local storage data for the domain as soon as a page containing Helium/VA (ult-inwebo.com) is displayed.

Helium Backup is considered as a “third party browser extension” by Internet Explorer. If the mechanism doesn't work on your computer, please verify the following points :

• Are third party extensions enabled ?

  • click on the settings icon or menu, and go to 'Internet Options'

  • in the Options window, go to the 'Advanced' tab, and in the 'Browsing' section find the 'Enable third-party browser extensions' parameter. The option must be checked for Helium Backup to work.

• Is the extension enabled ?

  • click on the settings icon or menu, and go to 'Manage add-ons'

  • check that Helium Backup is displayed and its status set to 'Enabled'. If not, right click on it and choose 'Enable'
