I did not ask you about that. I'm not interested in putting more information in the cloud and I have different sets of bookmarks on different computers depending on use.

What I asked was if there is a way to transfer the bookmark toolbar content from one to the other. If you can't answer that, please don't answer.

To copy your bookmark bar to your new computer, sync your browser account on both devices. This will ensure all bookmarks, including the bookmark bar, are transferred. Alternatively, you may need to recreate it manually if syncing isn't an option.

Somebody else answered incorrectly, I replied, you ignored that and gave that same, unasked for answer again.

Note that the Bookmarks Toolbar bookmarks may have ended up at the bottom of the Bookmarks Menu folder, so you can possibly do a search to see if you can locate them.

In Firefox 96+ you can right-click a bookmark search/query/recent result list and click "Show in Folder" to locate this bookmark in the folder list in the sidebar.
