When trying to automate the loading of an extension for work, I am trying to use Pywinauto. I found a great YT but it is using Notepad not Firefox. So there will be some changes and I am fine with trying to sort that out.

My issue is when I go to about:debugging#/runtime/this-firefox and then in my script I run:
app.MozillaFirefox.print_control_identifiers()

And get a list. But that list does not have the button that is titled: Load Temporary Add-ons.

I have copied the list out to N++ to search easier for Load or temp but nothing is found.

Where did I go wrong? Any pointers are appreciated.
