Someone already reported it there: https://www.reddit.com/r/firefox/comments/mc8vyx/pocket_disappeared_from_the_library_dropdown/ There is currently no way to view websites saved to pocket. Only integration is that one button visible on address bar and I have no idea how to restore it after you remove it. I hate their clumsiness. This is second time they remove one thing and forget to add replacement/config in time. Previous case was something with bookmarks menu if I remember correctly, and they still did not add any option to right-click-menu.
