A wonderful Add-On, I love it and use it since many years.
Alas, in the latest Version 11.0.41, there seems to be a severe bug.
When saving complete web-pages (with pictures), FF 68.12.0esr freezes for quite a while.
Then, in the download log, it says "failed".
When I press the redo-button, saving works instantly.
With NoScript deactivated, saving works normal.
Without that, I had given 5 stars.
Hoping for improvement, for this is really annoying.
