Hi Thank you for your question. I understand what you are getting at and I think it is a good query. As far as I am aware, it makes no difference. Once they have been imported into Firefox, the "from IE folder" is just a designation to let you know which ones have been imported across. It should not make any difference to the performance of Firefox and you and easily manage bookmarks out of that folder into others if you wish to (more details on how to do this can be found [https://support.mozilla.org/en-US/kb/bookmark-folders-organize-your-bookmarks here]). I hope this helps, but if not, please come back here and we can look into a different solution for you.
