Title: Added SSM compatibility

There you go mate.

I have added 2 fix:

1 - Added the same CSS fixed that I used in save_and_return (i.e. vs. )
2 - Since your extensions uses JS to create the button, I simply added a simple if clause to check if we are in the SSM (i.e. )

You are free to use both or only one.
