On new Add-ons manager with the fix on bug 585950. When I want to remove each extension, It is necessary to change the view. So, "Remove"and "Check for updates" should be provided for extension in context menu in "List View". The reason, 1. "Remove" button is removed from the list view. 2. Reduce the transition of the screen as much as possible. 3. Scroll position of the list view does not persist when return from the detail pane.
