Librewolf Small Issues


I usually use librewolf but i had several issues and was wondering if any of you knew how to tackle them. The first and by far the most annoying is when login into a site the manage passwords by librewolf is on top of the menu and many time I hit it accidentally. Is there a way to remove this option from the menu? The second is regarding the feature of opening new container tabs. Is there any shortcut for opening new tabs in a certain container?
