Not all bookmarks imported from firefox

Description of the issue:
Hi, having imported bookmarks from firefox, the result is, not all of them have actually been imported. Especially most folders from my bookmarksbar are missing (only the first one has been imported). The rest haven’t been imported at all.

Expected result:
All folders and bookmarks to be imported + arranged in the same manner as they were in firefox.
