Multiple bookmarks can't be saved in their own folder

[Pareidol]

This is a Bug Report

Description

I often use the function CTRL+SHIFT+D to add multiple booksmarks in their own folder (e.g. if I do a research and want to add several tabs as bookmarks together in an own folder). Without the adon it works fine. If the adon is active, the new folder gets created in the designated folderpath (the "Default Bookmark Folder" folderpath), set by the adon, but all the bookmarks that should be inside the new subfolder, are in the "Default Bookmark Folder" as well, and not in the subfolder.

Steps to reproduce the problem

1. Open several tabs
2. Select multiple tabs
3. Press CTRL+SHIFT+D
4. Enter new foldername
5. Have a look inside your bookmark library, and search for the newly created subfolder in the "Default Bookmark Folder" folderpath.
6. Check if the bookmarks from your selected tabs are inside the subfolder.

Expected behavior

The bookmarks of the selected tabs should be created inside the subfolder, created from the firefox prompt, that is shown wenn you press CTRL+SHIFT+D

Specifications

• Version of the add-on: 3.1.0

• Firefox edition: Firefox (regular edition)
• Firefox version: 114.0.2
• Firefox language: German

• Platform/OS: Windows
• Platform/OS version: 11 Pro 22H2

Additional context

I use the implemented bookmark function.

I saw another strange behaviour regarding this topic:
When I add a new bookmark folder, the folder gets created in my "default-folder-path" all new bookmarks included. But directly after that, all the bookmarks from within this folder are getting moved directly in the "default-folder-path", leaving an empty bookmarkfolder that was just created.
