Unfortunately the View Pocket List menu entry in Bookmarks menu cannot easily be removed.
It will be removed if you remove the Pocket icon using the (right-click) contextual menu on the icon. The entry is not removed if you remove manually using the `about:config` way.

The normal/supported way to remove Pocket works fine: Right click the button, select "Remove from toolbar".
