Question

How can I fix a local storage access error in the plugin for Chrome?

Answer

This is caused by enablement of Chrome’s “block third party cookies” setting. To fix this error without disabling that feature, add an “allow” exception for the plugin.

 

Step 1: Get the ID of your Threat Response plugin.

1.1 Right click the plugin button and in the resulting drop down select Manage Extensions

1.2 The resulting page will have a URL like chrome://extensions/?id=ID_STRING

1.3 Copy that ID_STRING into your clipboard

 

Step 2: Create the allow rule

2.1 Go to Chrome’s cookie management page in settings (chrome://settings/content/cookies)
2.2 In the allow section, click “add

2.3 In the Site field, enter chrome-extension://ID_STRING/ replacing the ID_STRING with the string from step 1.3

 

Step 3: Verify

3.1 The Allow section of the cookie settings page should now have an entry for Cisco Threat Response Casebook.
