CloseReview for Session Manager by Mickey
Rated 5 out of 5 stars
This was the most important add-on I used until FF57. I have asked the author of this add-on if the API incompatibility is permanent (it reads so to me) or if he can rewrite the ap to be compatible.
The BIGGER QUESTION to me is was this crippling deliberate by Mozilla!?!? And if so, WHY???
