Plugin breaking Windows SSO #552
Description
Describe the bug
Using FF with this plugin I cant successfully login to our company ticketsystem servicenow with automatic login via the Windows company user. If I open the same URL in the "No Container" Tab Group everything works just fine.
To Reproduce
Not reproducable for you because ServiceNow user website.
Expected behavior
The SSO login should get me directly to the ServiceNow website instead of the Microsoft Azure AD Login webpage.
Screenshots
sorry, cant make screenshots of internal company websites.
Console outputs
If applicable, open about:debugging > This Firefox and select Inspect for this extension. Then copy and paste what is in the console (you can hide your private information, if any).
If you cannot find any errors there, try opening the browser console (hamburger menu > more tools > browser console).
Console Output from about:debugging. not really anything, its just one line regarding an image in base64. Nothing else wether I open the site in the "No Container" Group or in another normal container.

Firefox (please complete the following information):
- OS: Windows 10 22H2
- Firefox Version: Firefox Windows 139.0.1 (32-bit), packaged and distributed by my company. The Setting "Enable Windows SSO" in Firefox is forcefully enabled.
- Extension version: 11.11.0.200
Additional context
It seems to me the extension breaks the normal Windows SSO process, but sadly I cant debug or point to any particuliar error in a log. It saldy just doesnt work.
