Hello,

Install “Ignore X-Frame-Options Header” Firefox Add-on

This is a Firefox add-on that can be used to achieve the same results if you do not have access to the web server.

Installing this Add-on will let you bypass the x-frame-options policy and allow the website to be loaded in the iframe.

Hope it works. Thanks.

Now I'm getting another error - See Attachment

Did you open another browser at the same time, If it's not then try clearing cookies and sites data.

• Click the menu button. and select Options. Preferences.
• Select the Privacy & Security panel and go to the Cookies and Site Data section.
• Click the Clear Data… button. The Clear Data dialog will appear. ...
• Click Clear.

I'm not sure we're using the same Firefox. I have looked everywhere I know to look and cannot find a "Menu" button so I can't even begin doing what you ask. I'm using 77.0.1 (64-bit) I mean it, I have looked everywhere for a menu button Jerry

Ok, I found the menu and followed through and deleted the cookies and data.

Still getting the same message.

Its 3 vertical bars look at my mouse cursor in attached screenshot.

I found it and followed through. I'm going to uninstall Firefox, reinstall it and if I have the same problems I'll use Chrome.
